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). A look at the journal shows:
simular here on an Intel HD Graphics 530 (GT2) Gen 9 (Gnome, X11), mostly a
immediate freeze during web browsing.
CRTL+F3 and dmesg shows what's up.
note:
I'm mostly running lastest homebrewed vanilla kernels (with GPU firmware loaded),
currently 5.11.
so I guess you will see this with fedora kernel 5.11 too (if not somehow patched away),
cause this GPU hangs have a history.
IMO, they were completely away around 5.9 (?) and came back with 5.10.x (?)
moons ago I tested with/without GPU FW on Fedora kernels: no differences
anyway, I'll test what @ED Greshko suggested.
