Reproduction Steps

Download test video with yt-dlp:

./yt-dlp_linux -f 303+251 https://youtu.be/6opX6gBL5gA

Run mpv with --hwdec=auto:

mpv --hwdec=auto Deputy\ Spike\ Feresten\ \[6opX6gBL5gA\].webm

Reduce playback speed until stuttering stops.

Expected Behavior

No stuttering.

Actual Behavior

mpv_vaapi_stuttering.mp4

In this recording, I tested the playback speeds 0.23 and 0.25 (0.91 and 1.00 with a multiplier of 0.25). Stuttering at 0.23 but not 0.25.

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

• I tested and confirmed that the issue exists with the latest release version or newer.
• 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.

Contact your distro for support instead. mpv upstream only provides support for the latest tagged release or newer

And your vaapi driver and 3d acceleration driver are somehow from two different versions of Mesa, so your system is just broken in non-trivial ways on top of that.
