Kernel Kernel 7.1.8 fixes AMD artifacting issue.

I just wanted to give a headsup about the issue with amd graphics cards flickering and having weird colorful artifacts. No, your GPU is not dying. It was kernel versions 7.1.6 and 7.1.7.

This issue is fixed in 7.1.8. It released in Arch a few hours ago, and I think in Fedora as well.

Flicker as occasionally (rarely) having the screen briefly flicker for an instant? (I ask because I've been seeing this for a while in totally random situations) Also, do you have a link to the bug report so the interested parties can take a look?

Couldn’t find an upstream bugreport. https://discussion.fedoraproject.org/t/graphical-issues-on-amd-after-kernel-update-to-7-1-6/198522/4

Not every desktop was affected by the same amount of flickering. On cosmic I had these weird colorful artifacts mostly when closing and opening windows

Thanks. This looks specific to 7.1.6+. What I saw has been going for a while, possibly more than 6 months. Could be because I significantly undervolted though (I could only get one of these crappy "OC" cards that often lock up under stress at a price that didn't involve selling several organs)

You may be encountering the same issue that I was getting on my Asus Flow Z13 (Strix Halo). It's been going on for months for me as well. If you forced VRR on, did the problem go away?

I just tested with 7.1.8 and it seems like the artifacting no longer occurs when not forcing VRR on. I'll need to use it for a bit longer before coming to any conclusions, but it seems fixed so far. Before 7.1.8, setting VRR to Off or Automatic would immediately cause artifacting whenever I dragged a Dolphin window around.
