Created attachment 145737 [details] Screenshot of the artifacts SUMMARY Running plasma wayland on the proprietary nvidia driver through gbm. The panel and all its applets, the application launcher, the volume dialog all have graphical artifacts when using the Breeze "Plasma style". Some different themes, both solid and transparent/blur, do not have the same issue (though many do). Screenshot of the artifacts: https://puu.sh/ID0SI/2501435977.png Not visible in the screenshot is the application launcher animation which leaves a black trail behind when hiding. Example of a translucent theme that works correctly: https://store.kde.org/p/1659742 SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Fedora 35 (available in About System) KDE Plasma Version: 5.23.5 KDE Frameworks Version: 5.90.0 Qt Version: 5.12.5
