I’ve been experiencing moderate graphical glitches for a while now. While I was communicating with support on hardware issues, a Mesa update caused glitches not just for me, but for many other people as well. Since some time has passed, I want to know if others are still experiencing graphical glitches like I am right now, so I can tell if this is an issue unique to me.
The glitches I’m experiencing are, concretely:
- Brief half-screen single-colour flashes
- Brief whole-screen flashes, particularly when displaying bright colours
- Glitched rectangles briefly appearing during animations or video playback, particularly in the lower half of the screen
- Occasional screen tearing in the lower half of the screen
These glitches occur on my desktop, mostly. They don’t occur when I’m playing full-screen games, with the possible exception of screen tearing, but that happens rarely and I haven’t seen it when gaming yet.

Im on 6.17.6-300.fc43 with Fedora 43. FWIW I am no longer seeing the artifacts as of the current versions I am on.
However, when I did see them, I did some research (and shared it in the thread that is basically identical to this) and there is a workaround - note, it will reduce battery life:
I used to use amdgpu.dcdebugmask=0x410 within my kernel parameters. This disables the powersaving features that can cause the issue.
ymmv
I’ve also been seeing the whole-screen flashes, which are driving me nuts. I think it may be related to my docking station and 4k monitors, as I haven’t been able to find a solution yet. Feeding my logs into Claude, it’s indicating that I should try reducing my refresh rate to 30Hz, but I really don’t want to do that 
.
Note that the amdgpu.dcdebugmask=0x410 didn’t work for me, nor did amdgpu.runpm=0.
This is happening on the built-in screen.
I can report that neither amdgpu.dcdebugmask, nor amdgpu.runpm, nor disabling that power management feature in the firmware interface help.
I’ve had a few flashes of weird coloration (kind of hot pink, usually) that flicker in a thin line near the bottom of the screen. When I briefly tried Nobara it was much worse, with some full-screen green static-y flashes nearly every time I opened a program or switched between open programs. Now I’m firmly on Mint and the flickers are extremely rare, but I’m also not pushing my graphics very hard even when gaming.

I had a similar issue on the built in screen. I was running Ubuntu at the time. I loaded up bazzite and that seemed to fix it.
Maybe try booting to another distro on a USB and see if the glitches still happen?
