Reference image of the bug as visible on ohm. Captured 2026-05-08 via
mpv --hwdec=v4l2request --vo=dmabuf-wayland --pause --start=00:00:00.42
--fullscreen fourier-test/bbb_1080p30_h264.mp4 then spectacle -b -f -n.

Uniform dark green at approx RGB(0, 75, 0) — exactly what the all-zero
NV12 hypothesis (Y=U=V=0 through BT.601/709 conversion) predicts and
what marfrit/dmabuf-modifier-triage#1 diagnoses (KWin reads past-EOF
on the UV plane fd, returns zeros for chroma).
