Green artifacts screen flickering

green display artifacts keeps occuring when browsing or scrolling, been occurring since december

system is framework 16 amd cpu 7840 graphics are integrated. any assistance how to stop or reduce it. flickers almost every 15 minutes

I’m also using a Framework Laptop 16 and found that adding the following argument to the grub kernel entries help alleviate some of the issues:

amdgpu.sg_display=0 [1]

It doesn’t eliminate them, but it keeps them a bit more at bay especially after upgrading to the 6.12.x kernel versions.

There have been folks on this site with AMD GPUs that also tried adding amdgpu.dcdebugmask=0x10 as an argument as well. I don’t know if it’s made an improvement for me.

Unrelated the graphical glitches, you can enable additional refresh rates by adding amdgpu.freesync_video=1.

Which did you find actually made the difference for you? I have been having the same issue on my Framework 16 and started thinking my GPU was bad.
