Screen Flickering After Update to Kernel 5.9.1

Brief summary of the problem:

I upgraded to Linux Kernel 5.9.1 today, and after the upgrade the screen flickers with black bands across the screen. They get worse when I move the mouse or type on the keyboard. I have tried to force mode setting in my boot parameters (using "video=DP-1:2560x1440@144") but that does not help. I upgraded from kernel 5.8.9 which did not exhibit the issue.

The flickering stops if I lower the refresh rate from 144Hz down to 60Hz. Anything above 60Hz (75 and 120Hz) exhibits the same issue.

I get several amdgpu errors in dmesg (entire dmesg amdgpu entries attached):

[    4.822286] [drm:amdgpu_dpm_enable_uvd [amdgpu]] *ERROR* Dpm enable uvd failed, ret = -5. 
[    4.839791] amdgpu 0000:0c:00.0: amdgpu: Msg issuing pre-check failed and SMU may be not in the right state!

...

[    4.992054] amdgpu 0000:0c:00.0: amdgpu: Msg issuing pre-check failed and SMU may be not in the right state!

Please let me know if there is anything I can try to help fix this or if you need additional info.

System infomration:

  • Distro name and Version: Arch Linux
  • Kernel version: 5.9.1-arch1-1
  • Custom kernel: N/A
  • AMD package version: No package

How to reproduce the issue:

There are no special steps to reproduce the issue. As soon as I boot the system, the flickering starts before I enter a desktop environment. Whatever desktop environment / window manager I use exhibits the issue.

The flickering stops if I downgrade to my last kernel (5.8.9-arch2-1) or lower the refresh rate to 60Hz.
