The decode surface is DXVA-aligned (height rounded up to the profile's
alignment, 128 for HEVC/AV1), so it is taller than the frame: a 2400-line
stream decodes into a 2432-line texture. VideoProcessorBlt was called with
no stream source rect, so it blitted the WHOLE surface — the uninitialized
padding rows (NV12 Y=0,U=V=0, which converts to vivid green) landed at the
bottom of the output and the picture was squashed to fit. Set the source
rect to the real frame.
Pre-existing on this backend, but 40030e90 made D3D11VA auto's first choice
on Intel, so it went from a corner case to what every Intel user sees — a
~32 px green bar at 3840x2400, reported on glass within the hour.
Also dedupe the Settings GPU picker by description: that string IS the
identity downstream (persisted as Settings::adapter, matched by name as
PUNKTFUNK_VK_ADAPTER), so repeated enumerations of one adapter offered the
user the same choice twice — live on an Intel Arc laptop, whose Vulkan ICD
also enumerates the single physical iGPU twice. Both paths now log their
raw enumeration (decode texture dims; DXGI name/LUID/ids) for the next
report.
