- Issue started after the following happened: I tried dmabuf-wayland because I had frame drops in fullscreen on gpu-next and all other VOs.

Reproduction Steps

Run mpv --no-config --vo=dmabuf-wayland --log-file=mpv.log ./South.Park.S28E01.Twisted.Christian.1080p.AMZN.WEB-DL.DDP5.1.H.264-NTb.mkv or any other video file I tried, then go to fullscreen. The colors look off (green seems to be brighter) unless you move the mouse to show OSD or any subtitles are shown, then the colors return to normal until the subs or OSD disappear.

From the log file it looks like it could be an issue with direct scanout.

Expected Behavior

Colors should look the same whether subs/OSD is shown or not.

Actual Behavior

Colors look weird when there are no subs or OSD in fullscreen, green is darker and red brighter than normal.

Log File

This logfile is without --gpu-debug, because I literally looked at the bug guide on https://mpv.io/bug-reports/ and it didn't mention anything about that flag and right now I am not at that machine.

mpv.log

Sample Files

Happens with multiple files, I only tried mkv files. I cannot show a screenshot because the issue disappears as soon an I try to take one.

I carefully read all instruction and confirm that I did the following:

• I tested with the latest mpv version to validate that the issue is not already fixed.
• I provided all required information including system and mpv version.
• I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
• I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
• I attached the full, untruncated log file.
• I attached the backtrace in the case of a crash.

Reproduce the issue with the exact mpv --no-config --vo=dmabuf-wayland command and inspect the attached mpv.log, especially the direct-scanout behavior in fullscreen. Compare output with and without subtitles or OSD; done means colors remain consistent in all three states.
