Are you using a non-default Plasma style?

Does the issue ever reproduce in a new clean user account?

I'm not using no-plasma them.
I test with.new account this week-end

Got more reports, re-opening.

At least one affected person was using the default Breeze theme. If everyone else as well? Or is anyone using a third-party theme?

does this still happen? all bug reports seems on 6.1, and theme.cpp is changed a lot since then

Not anymore for me. (There are generally far less plasma crashes than 6 months ago.)

That's great news to hear! Thanks for following up.
