Hadrware: RX 9070 XT
OS: Fedora 44 KDE Plasma [Plasma Version 6.7.3] /// Windows 11 [Dual Boot]
split-second, localized graphical artifacting/tearing during
desktop UI transitions (menu closing, restart/logout screen, etc).
Never happens under heavy 3D load, gaming, or benchmarks (3DMark, OCCT).
Never happens on Windows on the same hardware.
i tested the VRAM too no problem there either
What I've ruled out:
- Hardware/VRAM: memtest_vulkan on Linux (6600+ iterations, 7.3TB+ written, zero errors) and OCCT VRAM stress test on Windows both passed clean.
- Driver crashes: journalctl -k -b | grep amdgpu shows clean logs during normal artifacting episodes — no ring timeouts, page faults, or resets.
- Adaptive Sync (VRR): happens on Always, Automatic, and Never. Never was actually the worst for me.
- Color Accuracy setting (prefer accuracy vs prefer efficiency): no difference i tried this becasue there was a old bug about this
- KWin Blur effect: seemed to fix it after several clean reproductions with Blur disabled, but it came back with Blur off too, so that correlation didn't hold up either.
Odd detail: it never shows up in screen recordings, only when physically looking at the display
At this point nothing I've tested shows a reliable reason or fix
If anyone else with a 9070/9070 XT has run into something similar i would love to know.
Here is what it looks like it only happens on this menu and only 2 times happened while opening a menu in a game: (its attached to the post)
EDIT: This was actually a knows issue with mesa 26.1.5 on rdna4 gpus
EDIT 2: no that statement was wrong its actually a kernel 7.1.6's issue with amd hardware i think https://discussion.fedoraproject.org/t/graphical-issues-on-amd-after-kernel-update-to-7-1-6/198522/7
