Some strange error periodically happens, it leads to mouse cursor freeze for 5-10 seconds, the following records appears in the log:

After a long freeze the system resume normal operation, mouse also resume normal operation.
The only running process is chromium-browser with no opened tabs (start page only). The issue happened when I move cursor over minimize button on the window title.
The same issue periodically happens with different scenarios.
@popcornmix / @pelwell This should probably be transferred to our Linux repo?
Maybe. My gut feel is the __vb2_queue_cancel WARN is not causing the mouse pointer freeze for 10-15 seconds, and is possibly harmless (@6by9 may be able to clarify).
The vc4-drm gpu: swiotlb buffer is full may be more likely related to the mouse hangs. @pelwell what causes that? Is it just a (some sort of) memory is full issue? In that case it may be more a bookworm issue than a kernel issue.

Correct, it's videobuf2 complaining that the driver hasn't handed all the buffers back, but after warning it then cleans up on the driver's behalf. Why just the start page kicks off a video decode is a little curious though. What do you use as your start page?
before opening firefox with start page, I was opened some apps, don't remember exactly, but they all was closed at the moment of issue. There was also VLC running network streaming (internet radio), but it was paused 5-10 minutes before issue and minimized into tray.
VLC was started with command line:
vlc --qt-start-minimized https://strmreg.1.fm/chilloutlounge_mobile_mp3
Is it possible that minimize to tray has some issue?
just to keep issue up.
With latest kernel rpi-6.6.y and all latest upgrades, the issue still present:
