--- Comment #1 from Zamundaaa <xaver.h...@gmail.com> ---
Color information on the surface does not differentiate between compositing and
direct scanout. The transfer function not being supported does not make a
difference for this bug.
On my desktop, this caused a kernel nullptr dereference, so I couldn't test it
there, but on my laptop there is no visible difference between compositing and
direct scanout.
Are you using night light? Please also attach the output of
> kscreen-doctor -o
and (ideally run it while the video is getting direct scanout)
> drm_info
