Hi Michael, That did the trick, many thanks! I have not seen the crash you describe in the links; The script I think is just a warning, but in my case the behavior of the task bar is warning enough, I think. Thanks again, regards, Jogchum
It's hard to say for sure from reading the symptoms, but it reads a bit like a problem I encountered.
When plasma errors it sometimes silently switches to a software renderer. If this has happend, check ~/.config/kdeglobals and remove:
[QtQuickRendererSettings] SceneGraphBackend=software
I've posted concerning this on KDE Discuss: https://discuss.kde.org/t/on-error-kde6-x11-switched-to-the-software-rendere... https://discuss.kde.org/t/wayland-kwin-crashes-when-i-alt-tab/12730/10?u=dig...
I run the script quoted in the second link that checks for this on each login.
Michael
