The last 2 or 3 kernel updates seem to have triggered a regression in the i915 (internal Intel GPU) driver. I get damaged screen updates, very noticeable tearing on videos and occasional freezes in the DE (Plasma under X11).
Same here, I had to rollback to using kernel-5.9.16. Haven't tried any 5.10's since 5.10.13 or so (all up to there was pretty busted on my hardware).
