Created attachment 187396 [details] example of the graphical bug SUMMARY I woke my PC from sleep mode and these rectangle graphical glitches were scattered across the whole wallpaper on both displays, the panel, and the tray icons, but NOT on top of Task Manager icons nor Folder View icons. They also appeared differently placed over the firefox windows I had opened when I viewed them. The bugs went away there when switching tabs. Nothing changed on the wallpaper, panel, etc. until I restarted plasma with "kquitapp6 plasmashell && plasmashell" which removed the glitches. I believe I can safely assume logging out and back in would produce the same effect. I've had similar rectangle glitches before in earlier bugs in Plasma, so I'm pretty certain it has to do with Plasma having an issue with my Nvidia GPU. STEPS TO REPRODUCE 1. Go into sleep mode. 2. Wake from sleep mode. OBSERVED RESULT Graphical glitches appear covering wallpaper, panel, and tray icons after wake from sleep until restart plasmashell EXPECTED RESULT No graphical glitch rectangle things SOFTWARE/OS VERSIONS Operating System: EndeavourOS KDE Plasma Version: 6.5.3 KDE Frameworks Version: 6.20.0 Qt Version: 6.10.1 Kernel Version: 6.12.60-1-lts (64-bit) Graphics Platform: X11 Processors: 16 × AMD Ryzen 7 7800X3D 8-Core Processor Memory: 69 GB of RAM (66.6 GB usable) Graphics Processor: NVIDIA GeForce RTX 3090 Ti Manufacturer: Micro-Star International Co., Ltd.

I'm afraid the problem is in the proprietary NVIDIA drivers. You may be able to manually fix it by following the instructions at https://community.kde.org/Distributions/Packaging_Recommendations#Proprietary_NVidia_driver_configuration. If you've already done those steps, or they don't fix it, then it't just an NVIDIA issue. In that case, please report this issue to the NVIDIA folks, either by sending an email to linux-bugs@nvidia.com or making a post at https://forums.developer.nvidia.com/c/gpu-graphics/linux. It would be helpful to the NVIDIA developers if you could run nvidia-`bug-report.sh` and attach the resulting file in your report. Thanks!
