(In reply to sigsys from comment #5)

I've been suffering from this issue on a Ryzen 9 4900H with embedded
Renoir graphics using drm-61-kmod-6.1.92_2 on stable/14-n268738-048132192698.
Playing videos using mpv easily triggered the slowdown after some time
(especially 4K videos).
I've implemented the suggested fix and now I cannot reproduce the behaviour
anymore (tested for 2 days now). Even playing multiple 4K videos in
parallel does not cause the problem.
Thanks for the fix.
