Hello everyone, i just updated to the new touchscreen on my Framework 13 laptop and the overall experience has been amazing. However, it appears that sometimes graphical glitches occurs on the screen when i’m toggling fullscreen on some application. I can be on the application itself or all over the screen on a small section. I though it was due to the last update of Plasma on Fedora 44 but it seems not be the case. Do you think it could be a malfunction on my new screen ? Is anybody encountering the same issue ?
Thank you !
Those look like GPU artifacts. Could be the same AMD driver update issue that is common in the FW16 forum lately.
The issue is related to adaptive refresh rates and the touchscreen supports that.
Try changing the Adaptive Refresh setting in the KDE display settings to “Always”

I’ve got those same artifacts on my new 2.8k screen also with an AMD 7040 and setting it to always use adaptive refresh does seem to work around the problem. I’m on kernel 7.1.3 (currently the latest upstream). Do you know if anyone has filed a report on this yet?
EDIT: Putting amdgpu.dcdebugmask=0x400 (which, if my understanding is correct, disables panel replay and falls back to panel self-refresh) on the kernel command line also seems to work around the problem without the other side-effects associated with using VRR all the time.

That did the trick for me, thanks for posting.
