On-glass (Mac ↔ Windows M2c host): the host cursor's VISIBILITY is not a
usable 'a game grabbed the mouse' signal — Windows hides the pointer for
ordinary desktop activity (clicking, typing). The per-frame forwarder
turned those transients into relative_hint=true, so the client flipped
desktop→capture→desktop, which (a) warped the cursor to view-centre and
(b) flushed held buttons via releaseAll — a spurious mouse-up ~200 ms
into every press that broke window dragging/resizing.
Disable the auto-flip; the mouse model stays user-driven (⌃⌥⇧M). The
hint still rides the wire, unused, for a future M3 that keys off a REAL
pointer-lock signal (host-side ClipCursor/raw-input detection) instead
of visibility.
