It happens nearly without fail when right clicking the desktop, happens most of the time when minimizing a window, and happens sometimes when maximizing, moving, or closing windows. It also seems to get worse with time as the panel becomes more and more corrupted. Notifications experience the same issue, frequently becoming a box of random artifacts. No such graphical corruption issues when I had an AMD GPU in my system using the AMDGPU driver.</p> <p>Reproduction steps:<br> 1.) Log into Plasma Wayland session (latest stable 5.23.5 or beta 5.24, doesn’t matter) with Nvidia driver 495 or 510.<br> 2.) From what I’ve experienced is most likely to trigger it, right click the desktop or minimize a window a few times.<br> 3.) Observe graphical corruption on KDE panels and notifications.</p> <p>I’m not sure how useful this will be considering it should be easily reproducible internally, but I’ve linked a screenshot showing what it looks like (It’s random which pattern it has, just what I happened to capture) as well as the output of nvidia-bug-report.sh.
