Unstable Graphics on Fedora 33 with Kernels 5.10.9 and 5.10.10

Hi all, I have 2 systems (laptop and desktop) that seem to be behaving reliably after I put 5.10.16-200.fc33.x86_64 and i915.mitigations=off on each system. Time will tell if they remain graphically stable.

My desktop GPU chipset is the same as @sameyepatch and @anthonys53 so if your mileage is different, I would suggest running journalctl -b0 | grep mitigations and see if the i915.mitigations=off made it into the log without errors other than the kernel tainting message. I also took the defaults for the Compositor settings in System Settings.

Supposedly the 5.11.x kernels will have the i915 fix based on my earlier post with the link in it.

HI Anthony,
This has been fixed at redhat bugzilla. Still has not been merged into kernel. Here is bug: 1925346 – Screen glitches after updating to Kernel 5.10.10

To fix before it is merged into kernel, follow instructions on comment 13.
