Hello,
i have the Problem on an F34 and F35 machine.
4k Videos shutter/lag in chromium.
To make this “easier” i tested with a local file - no youtube.
The only “real” error is in the End of this Thread.
Rest is Information about the System.

on f34 im using chromium-freeworld.
on f35 i tested brave and chromium-freeworld.
f34 is using libva-intel-driver > i965 > Intel(R) Pentium(R) 3558U @ 1.70GHz
f35 is using intel-media-driver (newer cpu) > iHD Driver > Intel(R) Core(TM) i5-8265U CPU @ 1.60GHz
Lets focus on F34.
Before we dive in >
If i play the test-video with mpv via
mpv --hwdec=vaapi --vo=vaapi /root/h264.mp4
Everything plays fine and smooth no lag, no shutter.

So Hardware Acceleration is working fine - it seems.
No Errors in the console output.
also i can see in intel_gpu_top - its working.

But i could find anything what is causing this error or how i could increase any buffer size or like that.
Maybe @akarshanbiswas knows or sees something?
i mean you are a legend on this vaapi support anyway.
