I have a machine with the exact same issue: black flickering on desktop wallpaper, but no flicker on apps and desktop widgets. I don't have Chatty or Steam and i can't reproduce the problem sistematically, it happen sometimes.... This issue is apparently wayland related because X11 session works well. This is a video recording of the problem: https://imgur.com/a/3r5Xhcg After a recent plasma update, now works better (flicker is less frequent and less visible) but not resolved. My system is: Operating System: Gentoo Linux KDE Plasma Version: 6.3.6 KDE Frameworks Version: 6.13.0 Qt Version: 6.9.1 Kernel Version: 6.12.31-gentoo (64-bit custom compiled) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 1800X Eight-Core Processor Memory: 31,3 GiB of RAM Graphics Processor: AMD Radeon RX 550 / 550 Series Mainboard Name: Gigabyte AX370-Gaming 5 Do you solve it?
As the black region doesn't cover widgets, this is definitely an issue in plasmashell, not in KWin
Could it be a GPU driver issue, Xaver?
(In reply to Nate Graham from comment #4) > Could it be a GPU driver issue, Xaver? I forgot to mention that it started doing this right after i updated the video card and switched the driver from radeon to amdgpu. I have another system with the same OS and configuration (but a different graphic card: HD6450) and works well. I don't think it's a GPU driver issue because only the desktop background is affected, not the apps nor the widgets.
