Thanks, that's a new idea I haven't thought of and indeed a temporary account works! Doesn't quite solve the problem yet but indeed a good starting point to try and figure it out. Edit: Was able to temporarily "fix" things (doesn't fix rendering issues, but makes desktop usable again) by reseting the panel configuration, and then some simple fixes to its appearance broke everything again... Sounds like it will be a while before Plasma 6 is ready for me to switch back to it.
