enricobuehlerandClaude Opus 4.8	3a33a69401	fix(kwin): select the custom mode KWin actually built, not the one we asked for ... A KDE host streaming to a phone-shaped client fell back to 60 Hz even though the 120 Hz mode was sitting right there in KDE's display list, one manual click away. KWin generates every custom mode's timing with libxcvt, whose first step is `hdisplay_rnd = hdisplay - (hdisplay % 8)`. A 2868x1320@120 request (iPhone 16 Pro Max) therefore becomes 2864x1320@119.92 — 4 px narrower, fractional refresh. We then asked kscreen-doctor for `mode.2868x1320@120`; its `findMode` matches a mode's id or its own `WxH@qRound(Hz)` name, so that string matched nothing, the select silently no-op'd, the output stayed on its sacrificial birth mode, and `size_applied` came back false → "KWin rejected the custom mode" → 60 Hz. Widths like 1920/2560/3840 are all multiples of 8, which is why only clients with phone-shaped panels ever hit this. Resolve the mode out of the output's OWN list instead and address it by kscreen mode id: exact height, width at most one cell narrower than asked, refresh within 1 Hz (which excludes the native 60 Hz entry). `set_custom_refresh` now returns the whole achieved mode, and `create` reports that as the output's `preferred_mode` — so the capturer's renegotiation gate waits for the size KWin will actually deliver and the encoder opens against it, rather than starving on the requested one. Also skip `addCustomMode` when a usable mode is already installed: kscreen-doctor APPENDS to the list and KWin persists it per output name, so the old code grew the user's display list by one entry per connect.

enricobuehlerandClaude Opus 4.8	24a24734eb	fix(inject/windows): follow the input desktop for pen + touch injection ... Same field report as the display-write fix, other half of the symptom: with a UAC consent prompt up — one the user could SEE in the stream, because capture already renders the secure desktop (326d6e17) — pen and touch did nothing, while mouse and keyboard kept working. The split was exactly which paths knew the input desktop can move. sendinput.rs reattaches, so mouse/keyboard reached the prompt. pointer_windows.rs had no desktop handling at all, so every InjectSyntheticPointerInput came back ERROR_ACCESS_DENIED: 22:20:31 virtual pen created (PT_PEN) 22:20:31 pen inject failed error=Zugriff verweigert (0x80070005) 22:20:42 touch inject failed error=Zugriff verweigert (0x80070005) contacts=1 Measured on glass before fixing, to find out what it actually takes: device on Default, thread on Default -> 0x80070005 (the field failure) device on Default, thread on INPUT -> OK device on INPUT, thread on INPUT -> OK The middle row is load-bearing: the synthetic pointer device is NOT desktop-affine, so rebinding the thread suffices and the device is never destroyed and recreated across a desktop switch — which would have dropped in-flight contacts and the pen's in-range state mid-stroke. Injection now retries once bound to the input desktop. The binding is scoped, not persistent like sendinput's: inject_pen/inject_touch_frame run on TWO threads (the caller's apply_batch and the refresh threads), and the batch caller is a shared task thread that must not be left parked on a Winlogon desktop that disappears when the prompt is dismissed. The first-failure WARN now carries the rejected sample (flags, pen flags/mask, pressure, rotation, tilt, position). A 0x80070057 INVALID_PARAMETER was seen once BEFORE any prompt existed and is still unexplained; the ranges all look sound on inspection (coordinates clamped to the virtual screen, roll/azimuth u16 so the modulo cannot go negative, tilt bounded 0..=90), so catching the actual offending sample is the way to find it. Verified on glass: with a consent prompt up, pen and touch now reach it — zero inject failures where every prior session failed immediately. A UAC prompt can now be dismissed from an iPad with the Pencil. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-24 00:36:51 +02:00
enricobuehlerandClaude Opus 4.8	b5fa878bc6	fix(pf-win-display): follow the input desktop so a UAC prompt can't refuse display writes ... Field-reported 2026-07-23: a consent prompt left up on an unattended host made the box unreachable. Every connect black-screened and failed after ~60 s, and the host had to be reached over SSH to clear the prompt. Windows refuses ChangeDisplaySettingsEx/SetDisplayConfig issued from a thread that is not on the desktop currently receiving input. While UAC (or the lock / logon screen) is up that desktop is Winlogon, and the host — which the service launches explicitly onto WinSta0\Default — got DISP_CHANGE_FAILED / ERROR_ACCESS_DENIED for every write. A session starting in that window could never set its virtual display's mode, so the capturer sized its ring to a stale mode, every composed frame was dropped for a size mismatch, and bring-up burned 8 retries before giving up. Measured on glass (RTX box, SYSTEM host in console session 2, real consent prompt up, virtual display active): INPUT desktop = Winlogon UNBOUND CDS_TEST -> -1 (DISP_CHANGE_FAILED) UNBOUND SDC_VALIDATE -> 0x5 (ERROR_ACCESS_DENIED) BOUND CDS_TEST -> 0 (DISP_CHANGE_SUCCESSFUL) BOUND SDC_VALIDATE -> 0x0 (ERROR_SUCCESS) New input_desktop.rs mirrors pf-inject's sendinput.rs retry model: issue the write, and only when it fails the way a wrong-desktop write fails, rebind this thread to the current input desktop and retry once. A working write is never touched, so the normal path is unchanged. The retry predicate stays narrow (ERROR_ACCESS_DENIED only) so the unrelated 0x57 exclusive-mode topology bug is not re-issued and mis-attributed. Unlike sendinput's dedicated injector thread, the binding here is SCOPED — a shared display-write thread left on a Winlogon desktop that is later destroyed would fail every subsequent write, which is the wedge this removes. Applied to all eight SetDisplayConfig sites and both ChangeDisplaySettingsExW calls in set_active_mode. The isolate site now decides its supplied config once, outside the write, so a retry re-issues the identical config rather than logging its escalation twice. A save is logged, because a silent one is indistinguishable in a field log from a write that never needed saving — which made the first on-glass verification of this change inconclusive. Both ACCESS_DENIED diagnostics now ask which cause applies instead of naming only the disconnected-RDP one: that phrasing sent this investigation chasing a phantom RDP session on a host that was already service-launched in the console session, while a consent prompt was the actual cause. Verified on glass: connect with a consent prompt up now reaches first frame in 3.0 s (was a black screen then "Connection failed" after ~60 s), with six "retried bound to it and it applied desktop=Winlogon" lines and rc=0x0 throughout.

enricobuehler	4b2d2d1e14	fix(gamescope/cursor): follow gamescope's own cursor verdict — the corner-parked pointer ... gamescope hides its pointer by WARPING the X pointer to the root's bottom-right corner pixel; it does not swap in a transparent X cursor, so XFixesGetCursorImage keeps handing back the last opaque arrow. The XFixes source picked its display by "whichever pointer moved", and a parked pointer never moves again — so it froze on the parked Xwayland and composited that arrow at (w-1, h-1): a sliver of cursor welded to the corner of the stream for the rest of the session while the real pointer went undrawn. Reported on-glass in every game (a game grabs the pointer, so the hide is permanent): "part of cursor shows up on bottom right ... isn't where it really is". Follow GAMESCOPE_CURSOR_VISIBLE_FEEDBACK instead — gamescope publishes it on every nested Xwayland root: 1 on the server whose pointer it is drawing, 0 on the others and 0 on all of them once the pointer is hidden. It answers both questions correctly for a STATIC pointer, which motion cannot: which Xwayland owns it, and whether to draw it at all. Read at connect, re-read on its root PropertyNotify (event drain now discriminates CursorNotify vs PropertyNotify) with a 250 ms resync as the self-heal. A pointer gamescope draws nowhere is published visible:false, not dropped — the encode loop overwrites the frame's overlay from this slot and strips invisible ones, so a None would leave the last visible overlay standing on repeat frames. Honouring the atom also gives the stream gamescope's own idle auto-hide, which this source never had. The pointer-motion heuristic stays as the fallback for a gamescope that publishes no verdict (logged at session start via cursor_feedback=false), so nothing regresses to a cursorless stream. Measured on a live 1920x1080 Steam Gaming Mode session (RTX 5070 Ti, gamescope c31743d+, --xwayland-count 2 --hide-cursor-delay 3000): idle 3 s => pointer (1919,1079) + feedback 0; real evdev motion => pointer live + feedback 1. End-to-end against that session the source now publishes visible=false while parked and tracks the live pointer within one 250 ms sample of motion. cargo clippy -p pf-capture --lib -D warnings and the 5 new pick_active tests are green at cargo 1.96.1 (CI parity); cargo fmt --all --check clean.	2026-07-24 00:31:55 +02:00
enricobuehlerandClaude Opus 4.8	bc5f6a3881	fix(apple/session): keep the display awake for the length of a session ... A stream is not user activity to the OS, and controller input does not feed the HID idle timer on any Apple platform — so a gamepad-only session reliably idles the panel out from under the user mid-play. A keyboard/mouse capture session masks the bug because those events are real local HID. The Android client has held FLAG_KEEP_SCREEN_ON while streaming all along; the Apple clients held nothing. DisplaySleepGuard is acquired in beginStreaming and released at the top of disconnect, so it is scoped to the session — every teardown path (user quit, sessionEnded, the backgrounded keep-alive timeout) funnels through disconnect. iOS/iPadOS/tvOS: UIApplication.isIdleTimerDisabled. App-wide and ignored while backgrounded, which is what the audio-only keep-alive wants. macOS: ProcessInfo.beginActivity(.userInitiated, .idleDisplaySleepDisabled), the Foundation wrapper over IOKit power assertions. That defers display sleep but NOT the screen saver, which runs off the HID idle timer independently — so a 30 s IOPMAssertionDeclareUserActivity heartbeat runs alongside it. Intended side effect: an idle-lock that follows the screen saver is deferred for the session too. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-24 00:00:55 +02:00
enricobuehlerandClaude Fable 5	6617275387	docs(env): stop teaching the compositor pin + uid-1000 anchors in starters ... Field triage (Nobara, Discord): the kde.md starter host.env told desktop users to set PUNKTFUNK_COMPOSITOR=kwin, which PINS the backend — detect() short-circuits and the capture-loss rebuild never re-detects — so a mid-stream switch to Game Mode killed the stream instead of following it. A follow-up hardcoded XDG_RUNTIME_DIR=/run/user/1000 anchor broke PipeWire for any non-1000 uid (pw audio connect: Creation failed). Revamp across every starter/example/reference: - Desktop starters (kde/gnome/hyprland/sway) shrink to PUNKTFUNK_VIDEO_SOURCE=virtual + an explicit warning that pinning disables session-following; forcing a backend is CI/appliance-only. - host.env.example: rewritten around auto-detection; anchors demoted to a commented ssh/cron-only block with the uid trap spelled out; the gamescope ATTACH/MANAGED knobs documented (previously missing); case-sensitivity called out. - packaging/bazzite/host.env + README: drop the uid-1000 anchors (a systemctl --user service inherits/derives them); README's stale PUNKTFUNK_COMPOSITOR=gamescope-era template synced to the real one. - packaging/kde/host.env: loud APPLIANCE-ONLY header (it pins on purpose). - configuration.md: session-anchors section inverted to "leave unset", compositor row states the pin consequence, case-sensitivity note. - troubleshooting.md: new "session fails right after editing host.env" section (case, wrong-uid anchors, stale pin, restart-to-apply). - gamescope.md/bazzite.md: attach/managed descriptions match current behavior (managed is the infra-detected default; attach re-modes a box-owned session to the client's resolution).

enricobuehlerandClaude Opus 4.8	bda015b101	docs(release): rewrite v0.19.0 notes for end users + set end-user notes voice ... Release notes were written for the people who build Punktfunk, not the people who use it — dense with protocol/ABI/type names that confused even technical readers. Rewrite v0.19.0 in a benefit-first, plain-language voice (New/Improved/Fixed) with all internal terms removed from the body and every protocol/ABI/embedder detail moved to a single bottom "Under the hood" section. docs/releases/README.md now codifies this voice as the format spec for all future notes.

enricobuehlerandClaude Opus 4.8	ec219763a6	fix(ci/release): make _release_notes_path POSIX-sh safe (deb/decky attach runs under dash) ... The v0.19.0 deb + decky release-attach steps source gitea-release.sh under `sh` (dash) and died with "Bad substitution" at _release_notes_path's `${BASH_SOURCE[0]:-$0}` — a bash array subscript dash rejects. So those legs never attached their assets to the release (the bash legs — apple, android, rpm — were fine, which is why the body still seeded and the DMG/.ipa attached). CI always sources this from the repo root, so resolve the notes as docs/releases/<tag>.md relative to CWD and drop $BASH_SOURCE entirely. Verified under dash.

enricobuehlerandClaude Opus 4.8	0dce1cd116	chore(release): bump workspace version to 0.19.0 ... Headline: the whole pen/tablet input stack (P0–P5) — a pressure-sensitive stylus plane across core wire, Linux, GameStream/Moonlight, Windows, iPad Pencil and Android. Plus touch-injection fixes, cursor-DPI scaling, three Windows-host display/cursor fixes, a gamepad same-PID conflict fix, and the Android mouse/keyboard (TV) regressions. Release notes authored in-repo at docs/releases/v0.19.0.md (first release on the new flow; CI seeds the release body from it). cargo update --workspace syncs the lock (versions only).

enricobuehlerandClaude Opus 4.8	c3c0115a82	fix(core/abi): bump ABI_VERSION to 13 for punktfunk_connection_send_pen ... The pen P0 work added a new embeddable C entry point (punktfunk_connection_send_pen) but left ABI_VERSION at 12 — the value 0.18.0 shipped. Per the project's convention (0.18.0 bumped to 12 for the additive cursor channel), additive C-surface growth bumps the ABI so embedders can gate on the new symbol. Regenerated include/punktfunk_core.h via cbindgen (cargo build -p punktfunk-core); WIRE_VERSION is unchanged (pen is capability-gated on HOST_CAP_PEN).

enricobuehlerandClaude Opus 4.8	00c8c12a0f	feat(ci/apple): export the iOS .ipa to the release + run artifacts ... The iOS leg archives with development signing and re-signs for App Store distribution at export time, but the existing export uses destination=upload (straight to TestFlight) and leaves no .ipa on disk. Add an export step that re-exports the SAME archive with destination=export to produce an App Store distribution-signed .ipa, then: * attach it as the `punktfunk-ios-ipa` run artifact on every build (upload-artifact@v3, since Gitea's backend rejects @v4), and * attach it to the unified Gitea release on vX.Y.Z tags (alongside the DMG), via the shared ensure_release/upsert_asset helpers. Same gate as the archive; warn+skip (never fails the best-effort iOS leg) if the archive is absent. Note: an App Store-signed .ipa installs only via TestFlight/App Store, not by direct sideload — it is a release/archival artifact.

enricobuehlerandClaude Fable 5	988b5742ec	fix(gamestream): tolerate NaN pressureOrDistance — VoidLink's finger touches were dropped whole ... The hex dumps from the on-glass session show textbook SS_TOUCH packets with pressureOrDistance = 0x7fc00000 (NaN): VoidLink encodes 'unknown finger pressure' as NaN (iPad fingers have no force sensor), and the anti-forgery finiteness gate rejected the entire packet — silently disabling the touch plane while pen (real Pencil force, always finite) worked. Coordinates keep the strict gate (they feed injector scaling); pressureOrDistance now sanitizes non-finite to 0.0, the spec's own 'unknown', which the pen path already maps to full-scale ink on contact.

enricobuehlerandClaude Fable 5	40611cd54d	debug(gamestream): surface the pointer plane's silent failure modes ... An on-glass 'touch does nothing' currently leaves NO trace: log the first SS_TOUCH per session at info (proves the client sends + we decode), and warn when a packet carrying a pointer magic fails the body parse (layout mismatch) instead of vanishing into the unknown-magic drop.

enricobuehlerandClaude Fable 5	98b97d7d76	fix(android/input): stop mouse back/forward leaking to nav + IME popping on hardware typing ... Two Android TV M&K regressions from the c90343c2 overhaul, both user-reported: 1. Mouse back/forward buttons doubled as Android navigation while streaming. The BUTTON_BACK/FORWARD motion edges already go over the wire as X1/X2, but Android's input reader ALSO synthesizes KEYCODE_BACK/FORWARD key events from those buttons unconditionally (stamped SOURCE_MOUSE, no FLAG_FALLBACK) — and the guard only swallowed the FLAG_FALLBACK variant, so the duplicate reached the BackHandler and yanked the user out of the stream. Swallow mouse-sourced BACK/FORWARD too; a remote/keyboard BACK is never mouse-sourced and still exits. 2. The soft keyboard popped up on physical-keyboard typing. KeyCaptureView (the always-focused IME/capture anchor) unconditionally claimed to be a text editor with a live editable InputConnection, so the TV IME counted input as active and showed its UI the moment hardware keys arrived. Gate the editor identity on imeShown (the user actually summoning the keyboard via gesture / remote toggle), with restartInput on both edges so the gate is re-read, and an onKeyPreIme BACK hook so an IME self-dismissal can't leave the gate stale.

enricobuehlerandClaude Fable 5	51792536d1	fix(pf-win-display): escalate CCD isolate to a keep-only supplied config on 0x57 ... Field bug (Steam Deck client, exclusive topology): every isolate retry failed SetDisplayConfig 0x57 with the physical panel left lit, while iPhone sessions worked — their virtual monitor's connected-set already had a sole-display topology persisted, so Windows deactivated the physical on hotplug and the isolate was a no-op re-commit (deactivated 0). The Deck's monitor identity had no such entry, forcing the live-deactivate path: supplying the doomed path (inactive, modes unpinned) plus its orphaned mode entries is rejected 0x57 by some driver/OS validation combos, so the retry loop could never converge — the prior mode-index unpin (5e088af7) was necessary but not sufficient on this box. Attempt 1 keeps the shipped shape; once a survivor is seen, later attempts supply ONLY the keep paths with the mode table rebuilt to just their referenced entries (indexes remapped, clone-shared entries deduped). The same host applies exactly this keep-only shape rc=0 whenever the DB has pre-isolated the virtual display, so the escalated shape is field-validated on the failing machine. The final attempt also drops SDC_FORCE_MODE_ENUMERATION — a real path removal drives COMMIT_MODES on its own. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-23 16:50:44 +02:00
enricobuehlerandClaude Fable 5	bf2c4456bb	fix(inject/windows): compact wire touch ids into slots — Moonlight native touch injected nothing ... On-glass report (iPad Moonlight vs the Windows host): pen inked, native touch did nothing. Cause: POINTER_INFO.pointerId was the client's raw wire id — Moonlight sends arbitrary large pointerIds, and synthetic-pointer injection rejects them (Apollo compacts ids into dense slots for exactly this reason); the failure was logged at trace, i.e. invisibly. Wire ids now map to the lowest free slot for the contact's lifetime, and the FIRST injection failure of a device logs at WARN (pen too) so an inert input plane is never silent again.

enricobuehlerandClaude Fable 5	c0f792ee8d	feat(android): pen P5 — stylus capture onto the pen plane ... The Android leg of design/pen-tablet-input.md §7: against a HOST_CAP_PEN host, stylus/eraser pointers split out of BOTH touch models (passthrough + gesture) into StylusStream — state-full samples with pressure, AXIS_TILT, azimuth from AXIS_ORIENTATION (Android's 0 = away-from-user IS wire north), AXIS_DISTANCE hover, both stylus barrel buttons, the eraser tool, and historical (coalesced) samples batched oldest-first. Kotlin heartbeats ≤100ms per the wire contract. JNI: nativeHostSupportsPen + nativeSendPen (flat 10-float stride, sentinels <0). No barrel-roll axis exists on Android — roll stays unknown here.

enricobuehlerandClaude Fable 5	c8aa3ed48b	feat(apple/ios): pen P4 — Apple Pencil (Pro) capture onto the stylus plane ... The flagship leg of design/pen-tablet-input.md §7: against a HOST_CAP_PEN host the Pencil splits out of the finger path (independent of touch-input mode) into PencilStream — state-full samples with force→pressure, altitude→polar tilt, azimuth (+90° to the wire's north-clockwise convention), Pencil Pro rollAngle→ barrel roll (17.5+), coalesced touches batched ≤8/send for full 240Hz fidelity, and Pencil hover (zOffset>0 distinguishes it from trackpad hover) as in-range samples with distance. Squeeze holds barrel 1, double-tap clicks barrel 2 (the Pencil has no hardware buttons/eraser — these are how host apps get those affordances). Implements the ≤100ms heartbeat wire contract (80ms timer) so a stationary held stroke survives the host's 200ms dead-client failsafe. Toward a pen-less host nothing changes (Pencil stays a finger). Also fixes hostSupportsCursor testing the STALE 0x04 bit — HOST_CAP_CURSOR moved to 0x08 when TEXT_INPUT claimed 0x04; the old test would mistake a text-input host (e.g. Windows) for a cursor grant and double-render the pointer.

enricobuehlerandClaude Opus 4.8	15d09a8c10	feat(ci/release): author release notes in-repo + announce stable releases to Discord ... Release notes now live in the repo at docs/releases/vX.Y.Z.md, authored during the version bump (before the tag). ensure_release (gitea-release.sh + .ps1 twin) seeds the Gitea release body from that file in the create POST, so the release is born WITH its notes instead of being created empty and PATCHed afterward. canary/rc have no file -> empty body, unchanged. New manual `announce` workflow (workflow_dispatch, tag input) re-syncs the notes file over the live release and posts a violet embed (title, notes lead-in, release-page link) to the Discord #releases channel via the DISCORD_RELEASE_WEBHOOK secret. Stable-only: a -rc tag is refused unless allow_prerelease=true. Pressing "go" is the quality gate, so a half-built or failed release is never announced. docs/releases/README.md documents the ritual; TEMPLATE.md is the skeleton.

enricobuehlerandClaude Opus 4.8	6cbc3eec8b	fix(sdl/cursor): scale the forwarded pointer to the video fit ... Parity with the Apple client (35c2c145): the SDL/Linux presenter built the host-forwarded cursor as an OS cursor at its native bitmap size, so the on-screen pointer tracked the HOST's display scaling — a 4K/high-DPI virtual display forwards a 96 px bitmap that then rendered huge on the client. SDL cursors are fixed-size from their surface (no draw-time scaling), so cache the shapes RAW and resample each by the live video-fit factor (min(window_px / mode) — the same aspect-fit `finger_to_content` uses) at install time, rebuilding when the serial OR the fit changes (a resize). The resample area-averages on premultiplied alpha so a transparent pixel's colour can't bleed into the fringe. The pointer now stays sized to the streamed desktop at any host scaling. Not yet eyeballed on a Deck/Linux box — SDL's HiDPI cursor sizing is version-dependent; validate on glass.

enricobuehlerandClaude Fable 5	45c9799aa6	feat(inject/windows): pen P3 — PT_PEN + PT_TOUCH synthetic pointer injection ... The Windows leg of design/pen-tablet-input.md §6, following Apollo's recipe: a per-session PT_PEN device (pressure rescaled 0..1024, polar tilt→tiltX/Y, barrel roll on rotation — Windows Ink renders Pencil Pro roll natively, barrel button, eraser via INVERTED/ERASER flags, hover) with a 40ms refresh thread against the ~100ms synthetic-pointer staleness auto-lift, plus a PT_TOUCH device closing the historical SendInput wire-touch no-op (full active-contact frames, per-id DOWN/UP edges, self-healing lost-DOWN synthesis). pen_supported now probes PT_PEN creation on Windows (1809+), which lights up HOST_CAP_PEN and the GameStream featureFlags there — Moonlight iPad + Pencil can ink on a Windows host.

enricobuehlerandClaude Fable 5	b192825869	feat(gamestream): pen P2 — SS_PEN/SS_TOUCH ingest, featureFlags advertised on capable hosts ... The Moonlight leg of design/pen-tablet-input.md §4: DESCRIBE now advertises SS_FF_PEN_TOUCH_EVENTS wherever pen injection exists (Linux+uinput, same gate as HOST_CAP_PEN — elsewhere the flag stays 0 and Moonlight keeps client-side mouse emulation exactly as today). SS_PEN packets merge over last-known state into state-full PenSamples (BUTTON_ONLY per spec carries no position; unknown contact pressure 0.0 inks at full scale; UP keeps proximity only for clients that demonstrated hover) and drive the same PenTracker→VirtualPen chain as the native plane — Moonlight iOS + Apple Pencil now exercises the full injection path end to end. SS_TOUCH forwards as wire touch on a synthetic 65535² surface with CANCEL_ALL replayed per tracked contact. No stroke timeout on this plane: ENet is ordered/reliable and Moonlight doesn't heartbeat a stationary pen. Packet layouts pinned against moonlight-common-c Input.h/Limelight.h upstream.

The Linux injection leg of design/pen-tablet-input.md: 0xCC/0x05 pen batches now route through the per-session PenTracker into a lazily-created 'Punktfunk Pen' uinput tablet (BTN_TOOL_PEN/RUBBER, pressure, tilt-from-polar, ABS_Z barrel roll, hover distance, INPUT_PROP_DIRECT) — compositors pick it up via libinput and hand apps zwp_tablet_v2 with full fidelity. The host now advertises HOST_CAP_PEN when /dev/uinput is accessible (PUNKTFUNK_PEN=0 kill-switch); transitions group into SYN frames so proximity-enter carries its position. Stroke failsafe: clients heartbeat ≤100ms while in range (documented wire contract — capture APIs are silent for a stationary pen); 200ms of silence force-releases. 'punktfunk-host pen-test' draws a pressure-ramped sine stroke through the real tracker→uinput chain, no client needed.

enricobuehlerandClaude Fable 5	248e1cbf08	fix(pf-vdisplay/driver): report cursor_excluded adapter-wide — the declare's exclusion is not per-target ... Field report (iPad via GameStream, 2026-07-23): cursor missing from the stream. The session's fresh target 257 reported cursor_excluded=false (DECLARED_TARGETS is keyed per target and only 259 had declared), so the host skipped forced-composite — but DWM's pointer exclusion after an IddCx hardware-cursor declare reaches EVERY later monitor of the adapter, not just the declaring target (proven on-glass: declare on 259 under WUDFHost 2192, then 257's frames streamed pointer-free with CURSOR_SHOWING set and SM_MOUSEPRESENT true). GameStream/Moonlight clients cannot draw a forwarded cursor, so those sessions were silently cursor-less. ADD replies now report any-declare-this-WUDFHost-life (the state's real scope — it dies with the adapter reset, same as before); per-target ids stay only as the dbglog audit trail. Channel-less sessions on a declared adapter then hit the existing forced-composite gate (GDI poller + blend) and carry the pointer in-video. Host code unchanged.

enricobuehlerandClaude Opus 4.8	35c2c1450e	fix(apple/cursor): scale the forwarded pointer to the video fit ... The Mac client drew the host-forwarded cursor bitmap at its native pixel size (pixel-as-points), so the on-screen pointer tracked the HOST's display scaling: a 4K/high-DPI virtual display renders a 96 px pointer, which then appeared huge on the client — and on retina every pointer was already 2x-inflated and upscaled-blurry, since the backing scale was ignored. Cache the shape raw and rebuild the NSCursor at the live video-fit factor (fit.width / mode.width — the same AVMakeRect fit the input mapping uses) on each apply, re-fitting on resize / retina moves. The pointer now renders at its true size relative to the streamed desktop at any host scaling: crisp and 1:1 with the video at 100%, and proportional (not ballooning) when the host sits at 200-300% — including a deliberately raised scale. iOS/tvOS (UIPointerInteraction) and Android (no forwarded-bitmap path) render the pointer differently and need no change; the SDL/Linux client has the same native-size issue and will follow.

enricobuehlerandClaude Fable 5	326d6e17c8	fix(windows/capture): stand the IddCx hardware cursor down while the secure desktop is up ... 0.18.0 regression: UAC consent and Winlogon (lock/logon) stopped appearing in streams. The cursor channel's IddCx hardware-cursor declare — re-issued by the driver on every swap-chain assign — keeps the path out of the OS's software-cursor mode, which is the only mode the secure desktop renders through; DWM then never presents UAC/Winlogon into our swap-chain and the stream repeats the last normal-desktop frame for the whole interaction. The GDI cursor poller now classifies the input desktop on its reattach cadence (UOI_NAME != Default = secure, 250 ms cadence instead of 2 s), and the capturer edge-triggers the existing-but-unused proto-v6 IOCTL_SET_CURSOR_FORWARD flip: OFF at secure entry (the driver stops its per-assign re-declare; the host facade forces the same-mode re-commit that actualises the software-cursor default, under the vdisplay manager lock via the new force_recommit()), back ON at dismissal for channel sessions. Channel-session open resets the driver's persisted desired state to ON so a session that died mid-secure-desktop can't leave the next one adopting UNdeclared (the §8.6 cross-session composite trap); orderly teardown does the same. The flip closure is built for every Windows session — a channel-less session can reuse a driver monitor whose earlier-session cursor worker still re-declares, and NOT_FOUND from never-declared targets is ignored.

enricobuehlerandClaude Opus 4.8	588a7077e8	fix(host/gamepad): only degrade a virtual Steam pad on a same-PID conflict ... The Steam-conflict gate matched any physical Valve `28DE` HID device, so a Steam Machine with a physical Steam Controller 2 (`28DE:1302`) plugged in degraded a client's requested virtual Steam Deck (`28DE:1205`) to a DualSense — the reporter's controller passthrough came up as the wrong pad. Steam Input drives *distinct* Steam controllers side by side; only two *identical* `28DE` devices confuse it (the Deck-as-host case: built-in `28DE:1205` + a second virtual Deck, observed live on Bazzite). Narrow the gate to key on the exact VID+PID instead of the `28DE` vendor alone: - `steam_backend_product()` maps each virtual Steam backend to the PID it enumerates as (Deck 1205, classic SC 1102, SC2 1302, SC2 Puck 1304). - `physical_steam_controller_present()` -> `physical_steam_product_present(pid)` matches `:28DE:{PID}`, keeping the FVPF-serial / `vhci_hcd` / `/virtual/` exclusions so our own virtual pads never count. - `degrade_steam_on_conflict` degrades only on a same-PID duplicate and logs the conflicting identity. `PUNKTFUNK_STEAM_FORCE=1` override unchanged. A physical SC2 no longer blocks a virtual Deck (and vice versa); a genuine same-identity duplicate (physical Deck + virtual Deck, or physical SC2 + SC2 passthrough) still degrades. Adds a unit test for the PID mapping. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-23 14:11:44 +02:00

Steam's "Add a Non-Steam Game to My Library" entries carry no `appmanifest`, so `scan_manifests` can't see them and they never appear in the streamed library. Read each Steam account's binary `userdata/<id>/config/shortcuts.vdf` directly (a binary KeyValues parse) to surface the user's own custom entries, plus their grid artwork from `userdata/<id>/config/grid`. Best-effort: an unreadable or absent shortcuts.vdf contributes nothing, and hidden shortcuts / duplicate appids are dropped. Verified: clippy -D warnings + compile green on Linux.

enricobuehlerandClaude Opus 4.8	8c9baf3214	fix(decky): recreate the library shortcut when its cached appId is stale ... The visible "Punktfunk" shortcut's Steam appId is cached in SteamUI localStorage, which lives in Steam's CEF profile — so it survives a plugin uninstall/reinstall. Deleting the shortcut left the key dangling; on the next mount ensure*Shortcut recalled the dead appId, took the reuse branch, and ran SetShortcut* against a non-existent id (silent no-ops). AddShortcut was never reached, so the entry never came back. The same stale-reuse also made the hidden stream shortcut RunGame a dead gameid. Verify the remembered appId still maps to a live shortcut via appStore.GetAppOverviewByAppID before reusing it; a confident miss falls through to AddShortcut. When appStore is unavailable, assume it exists so a false negative can't spawn a duplicate library entry. Also add a "Recreate library shortcut" recovery button to the QAM About section (recreateShortcuts): drops any dead cached keys and re-ensures. Covers deleting the shortcut without reinstalling, where no mount fires the self-heal. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-23 00:41:32 +02:00
enricobuehlerandClaude Fable 5	d83eeedde4	ci(flatpak): drop the use-vc TCP-DNS hack — the runner-side cache made it the failure ... Every flatpak Tooling failure on 2026-07-22 (4 runs, incl. two AFTER the runner fleet got its local dnsmasq cache) died in flatpak remote-add with an instant 'Could not resolve hostname' ×10 while dnf in the SAME container resolved fine. The one thing only this leg does is force glibc onto TCP DNS (use-vc) — a 2026-07-11 mitigation for the embedded resolver dropping UDP under fleet load. With job containers now resolving against the on-box dnsmasq cache (daemon.json dns → docker0), UDP is reliable again and the TCP path through the same chain is the flaky one under concurrency. Remove the hack; keep the nss-resolve drop and retry.sh as the backstop. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-23 00:27:52 +02:00

The cursor-channel sweep grew AddReply by the cursor_excluded u32 tail (24 bytes, legacy prefix 20) and bumped PROTOCOL_VERSION to 6, but left two lib tests behind: the AddReply byte-layout roundtrip still built the legacy initializer (a compile error that turned the rust CI leg red on main), and the version-coherence assertion still pinned v5 (hidden behind that compile error). Cover the new tail bytes + the legacy-size constant, and widen the compat-window note to v4–v6 (floor stays 3). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-23 00:22:34 +02:00

All transitive pins in the management-console tree; none ship in the streaming stack. Every fix version is in-range for its consumers, so: pin overrides for the single-major packages (tar/dompurify/linkify-it/sharp/fast-uri/immutable/ undici/postcss/js-yaml — bun ignores range-scoped override keys, so plain keys) and a full lockfile re-resolve, which also lifts brace-expansion 2.1.1→2.1.2 in place while its 5.x line (minimatch@10) stays untouched. : No vulnerabilities found.

enricobuehlerandClaude Opus 4.8	92f38ec3dd	chore(cleanup): drop TEMP cursor probes + clear KWin-leg clippy debt ... The KWin/Phase-A/B commits were built but never clippy-checked (that distrobox had no clippy component), so they left TEMP on-glass probes and lint debt in the tree. With clippy now runnable (fedora rust 1.96.1 = CI parity): - drop the `fec424ee`/`8cff30d5` TEMP probes: the `update_cursor_meta` SPA_META diagnostic logs (also un-detaches the `// SAFETY:` comment from its `unsafe` block → fixes `undocumented_unsafe_blocks`) and the KWin composite-arm probe in the encode loop. - `#[allow(clippy::too_many_arguments)]` on `spawn_pipewire` (8 params since the KWin leg added `expect_exact_dims`; mirrors `from_virtual_output`). clippy `-p pf-capture -p pf-vdisplay -p punktfunk-host --locked --features nvenc,vulkan-encode -- -D warnings` is now green. (--all-targets additionally trips a pre-existing env mismatch: the fedora libspa binding lacks `SPA_VIDEO_TRANSFER_SMPTE2084`, referenced only by a `#[cfg(test)]` guard-test — not a code issue; CI's pinned pipewire has it.)

enricobuehlerandClaude Fable 5	7058647264	fix(vdisplay/capture): channel-less sessions composite the pointer on a sticky-declared target ... A declared IddCx hardware cursor is IRREVOCABLE for its OS target's life (§8.6), and the sticky exclusion survives monitor REMOVE→ADD because each client gets a STABLE target id — so once any desktop-mode session declared, every later pure-capture session on that target streamed a cursor-less desktop: DWM excluded the pointer, no channel forwarded it, no blend drew it (the exact no-regression gap §8.6's per-session cap gate cannot see). Driver: track every successful SetupHardwareCursor per target (DECLARED_TARGETS — scoped to the WUDFHost's life, exactly the sticky state's scope) and report it in a new AddReply::cursor_excluded tail field (dual-size discipline, both skews degrade cleanly; no proto bump). Host: the flag rides AddedMonitor → Monitor → WinCaptureTarget; a session WITHOUT the cursor channel on a flagged target forces composite mode in the IDD-push capturer — GDI poller + blend for the session's life, pinned on (set_cursor_forward cannot clear it: with no client drawing, un-compositing would erase the pointer entirely).

enricobuehlerandClaude Opus 4.8	d5ae8dcc3e	feat(capture): gamescope cursor via XFixes shape + QueryPointer position (Phase C) ... gamescope excludes its pointer from the PipeWire node it feeds us and can't embed one either (`set_hw_cursor` is inert), so every gamescope stream was cursorless. Read the pointer from gamescope's nested Xwayland instead — XFixesGetCursorImage for shape/hotspot/visibility, core QueryPointer for position — and publish a CursorOverlay into the capturer's existing `cursor_live` slot, so the encoder blend composites it into the video exactly like the SPA_META_Cursor path. - pf-capture/src/linux/xfixes_cursor.rs (new): the XFixes reader. Connects to EVERY nested Xwayland (Gaming Mode runs one per --xwayland-count) and follows the focused one each tick (the display whose pointer moves), reading that display's own cursor shape. Un-premultiplies ARGB -> straight RGBA. Drop stops the thread. - Capturer::attach_gamescope_cursor + the PortalCapturer override spawn it into the same `cursor_live` slot; pf_vdisplay::gamescope_xwayland_cursor_targets discovers the (DISPLAY, XAUTHORITY) pairs via the GAMESCOPE_WAYLAND_DISPLAY scan. - host: SessionPlan.gamescope_cursor (set from the compositor at both resolve sites AND on a mid-stream Desktop->Gaming switch); the blend gate now builds the encoder blend for gamescope; a sibling composite arm attaches capturer.cursor() per tick for capture-mode clients (no channel needed). native NV12 is disabled for these sessions — that encode path can't blend the cursor (it assumes gamescope embeds the pointer), so we capture RGB and route to the proven CUDA VkSlotBlend / compute-CSC blend. - the pipewire thread no longer clobbers `cursor_live` with None on a buffer that carries no SPA_META_Cursor (gamescope) — that raced the XFixes writer and strobed the composited pointer on/off. On-glass (home-bazzite-2, RTX 5070 Ti, Gaming Mode): cursor visible + steady in Big Picture and CS2 menus, follows focus between the two Xwaylands, hidden in-game.

enricobuehlerandClaude Fable 5	925130d1f9	feat(vdisplay): compositor-embedded pointer for sessions without the cursor channel (Phase B) ... Since the cursor-channel work, every Linux virtual output was created in metadata pointer mode — making ALL sessions depend on host-side cursor compositing, including the ones that can never use the channel (Moonlight/ GameStream, legacy clients, capture-mode starts). Those sessions paid the blend bring-up per session and, whenever a visible cursor was composited, the loss of NVENC's stream-ordered submit — for a strictly worse cursor than the compositor's own. Mirror the Windows no-regression gate: the already-wired per-session set_hw_cursor(cursor_forward) now drives the Linux backends too. A cursor-channel session gets metadata (shapes forwarded, composite flip blends host-side — today's validated path, unchanged); every other session gets the pointer compositor-EMBEDDED at creation (KWin zkde pointer=2, Mutter cursor-mode=1, wlroots/hyprland portal CursorMode::Embedded — their pre-channel default; the portal pair also gains the Metadata arm for channel sessions, wired but untested on-glass). SessionPlan.cursor_blend narrows to cursor-forward sessions and rides into the direct-SDK NVENC open, which skips the Vulkan slot-blend bring-up entirely when off — embedded sessions ring on plain CUDA surfaces and pay zero cursor cost, per-session or per-frame. The keep-alive registry's reuse key grows the created pointer mode (new VirtualDisplay::hw_cursor getter): a kept embedded display has no cursor metadata for a channel session to forward, and a kept metadata display would leave a channel-less session with no pointer in its frames.

enricobuehlerandClaude Fable 5	d2c46eaf3c	feat(encode/nvenc): SPIR-V cursor blend over Vulkan-allocated input slots — retire the PTX kernels ... A vendored PTX blob is JIT'd against the driver's ISA ceiling, so the cursor-blend module silently dies on drivers older than the generating toolkit (CUDA_ERROR_UNSUPPORTED_PTX_VERSION/INVALID_PTX, 222/218 — the KWin leg's invisible composite cursor on driver 595/CUDA 13.2 vs a CUDA 13.3 blob). SPIR-V has no such coupling, and the in-tree precedent already exists twice (vulkan_video's CSC blend, VkBridge's exportable OPAQUE_FD → cuImportExternalMemory bridge). New pf_zerocopy::vkslot::VkSlotBlend: the direct-SDK NVENC encoder now allocates its input ring as exportable Vulkan buffers CUDA-imports (same contiguous InputSurface layouts, pitch = row bytes rounded to 256), and the cursor composite is a compute dispatch over the cursor's rectangle (cursor_blend.comp, vendored .spv; spec-constant selects ARGB/NV12/YUV444; BT.709 limited, matching the retired .cu). The surface SSBO is uint[] with every invocation owning whole words — no 8-bit-storage device dependency. Cursor-bearing frames force the existing CPU-synced submit path so the CUDA copy → Vulkan dispatch (fence-waited) → NVENC encode ordering is CPU-established; cursorless frames keep the stream-ordered fast path untouched. Any bring-up/alloc/registration failure falls back wholesale to plain pitched CUDA surfaces (never a mixed or short ring): sessions always encode, composite mode just loses the cursor, warned once. cursor_blend.cu / cursor_blend.ptx and the CursorBlend PTX loader are deleted.

On-glass (KWin leg) the blend module loads yet the composite cursor stays invisible — these two probes attribute it to no-overlay / stripped-en-route / kernel-draws-nothing.

enricobuehlerandClaude Fable 5	af87549052	fix(linux/vdisplay): KWin virtual outputs stream above 60 Hz via sacrificial-birth renegotiation ... KWin's ScreenCastStream builds its PipeWire format offer — including the maxFramerate cap it actively throttles delivery to — ONCE at stream creation, when the virtual output sits at its hardcoded birth 60 Hz. A kscreen custom-mode change afterwards updates the OUTPUT (readback says 240) but never the offer, so every consumer negotiates max=60 and the stream delivers 60 (pw-dump-verified on KWin 6.6.4). The only path that rebuilds the offer is the stream's own resize handling: a source SIZE change while recording re-runs buildFormats — picking up the output's current refresh — and renegotiates the live stream. So above 60 Hz, birth the output at a sacrificial height (+16), then install + select the real WxH@hz custom mode: the first frame recorded after the consumer connects triggers KWin's resize path, which renegotiates the live stream to WxH@hz. The capturer holds (requeues) buffers until the negotiated size matches — new expect_exact_dims plumbing VirtualOutput → registry (fresh creates only) → open_virtual_output → a self-disarming gate in the process callback — bounded by a 3 s deadline that accepts the producer's dims rather than wedging the session into the first-frame retry loop. set_custom_refresh reads back the full active mode; a size reject (pre-6.6 KWin) recreates plain at the real size @60. Every kscreen operation now addresses the output by its NUMERIC id, resolved by matching the managed name-prefix AND the just-created birth size (newest id wins): a mode-switch supersede reuses the per-slot output NAME (deliberately, for KWin's per-name config persistence) while the superseded sibling is still alive, and name addressing hit the FIRST match = the OLD output — on-glass that resized the live session's display out from under it (wrong-res/black), read the old output back as 'mode applied', and set the old output primary while the replacement starved at its birth mode.

enricobuehlerandClaude Fable 5	09113c9899	fix(encode/nvenc): cursor-blend PTX must carry a driver-portable ISA version ... The vendored cursor_blend.ptx was regenerated with the CUDA 13.3 toolkit, which stamps '.version 9.3' — and a driver whose JIT predates that ISA refuses the whole module with CUDA_ERROR_UNSUPPORTED_PTX_VERSION (222), silently killing host-side cursor compositing (on-glass: composite-mode cursor invisible on driver 595.58, KWin leg). The kernels use only baseline arithmetic, so hand-lower the version directive to 8.0 (CUDA 12.0), which every supported Turing+ driver JITs. Both files now warn that an nvcc regeneration re-stamps the version and must be re-lowered. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-22 23:47:53 +02:00

The frame-attached overlay is the pointer position at the last damage frame; repeats re-encoding a static desktop froze the blended cursor between redraws — on-glass the composite-mode cursor stuttered while window drags (constant damage) were smooth. Refresh the repeat's overlay from Capturer::cursor each tick so pointer-only motion re-blends at tick rate — the bandwidth the pre-channel embedded mode already paid. Linux only: the Windows capturer composites internally and its frames must never carry an overlay a blend path would double-draw.

enricobuehlerandClaude Fable 5	088004cac4	feat(linux/capture): serve the LIVE cursor overlay through Capturer::cursor ... The forwarder read only frame.cursor — the overlay attached to the LAST EMITTED frame. Mutter's pointer-only buffers update the capture-side cursor state but are skipped as frames, so between damage frames the forwarder re-sent a stale snapshot: on-glass the client cursor appeared exactly when clicking or crossing hover targets (damage) and froze/vanished otherwise — the same pointer-only-motion gap the Windows IddCx channel fills, which is why the encode tick already prefers the capturer's LIVE cursor. Publish the overlay from every dequeued buffer (frames or not) into a shared slot and implement the Capturer::cursor hook on PortalCapturer. Host-composite mode on Linux still updates the blended pointer only on damage frames (no re-encode of a static desktop on cursor motion) — the regen-on-cursor-change the Windows path has is a follow-up.

Mutter only rewrites a buffer's SPA_META_Cursor region when the cursor changed; recycled buffers between damage frames carry a stale id-0 meta. Treating id 0 as a hidden pointer flickered the client cursor off between hovers on-glass — per the SPA contract id 0 is 'invalid/no cursor info', so keep the last-known state (OBS's consumer does the same).

enricobuehlerandClaude Fable 5	9db4841ce4	fix(linux/capture): cursor meta size range must cover Mutter's fixed 384x384 offer ...

The intersection is empty, so the Meta param silently failed to negotiate and no buffer ever carried the meta region: the entire Linux cursor pipeline (forward AND blend) was blind on GNOME, proven by an on-glass probe counting 32k+ buffers with zero metas. KWin's offer fits inside 256², which is why the same consumer code passed there. Raise the max to 1024² headroom (the negotiated allocation follows the producer's value, not our max) and align the bitmap parse guard.

enricobuehlerandClaude Fable 5	0619af391e	fix(linux/inject): map absolute pointer/touch into the streamed output's region ... The libei absolute device advertises one region per logical monitor, and both MouseMoveAbs and touch mapped into regions().first() — whichever output the compositor announced first. Next to a physical monitor (on-glass: GNOME with a dummy HDMI beside the virtual primary) that put the pointer and every click on the WRONG output: the seat cursor never entered the streamed monitor, so neither embedded nor metadata cursor capture could ever see it, and the cursor channel had nothing to forward. Pick the region whose logical size matches the streamed mode (the wire flags already carry it); fall back to first() for the single-monitor case. Region geometry now rides the device-RESUMED log line for diagnosability; matching the screencast mapping_id instead of the size is the follow-up for same-sized-monitor ambiguity.

enricobuehlerandClaude Fable 5	afe120bf34	fix(linux/vdisplay): kwin virtual output ships the cursor as metadata too ... Same trap as the Mutter backend: zkde_screencast pointer mode 2 (embedded) never delivers SPA_META_Cursor, starving both the cursor channel and the encoder blend. Mode 4 (metadata) feeds both.

enricobuehlerandClaude Fable 5	c29186bd1a	fix(host+vdisplay): a mode-switch replacement display inherits the group topology ... The resize rebuild creates the new virtual display BEFORE retiring the old one (create-before-drop), so the registry saw a live same-backend sibling — its own dying predecessor — and told the backend it was not first in group. Mutter then skipped the Primary/Exclusive apply ("joining an existing display group — extending") and the retiring owner took the topology with it: every resize silently demoted the virtual output to an extended, shell-less desktop. Thread the superseded pool gen through acquire so the replacement establishes topology, and stop counting kept (Lingering/Pinned) entries as demoting siblings — no session owns them, so there is no live desktop to clobber.
