Created attachment 106593 [details] Only panel box shadow is showed some times, till all panels freezes Things are going wrong in latest updates of Plasma. Now, my "autohide" panel begin to show sometimes an empty rectangle when it's showed (the shadow of the panel, but no content). That occurs till all panels are freezed (I always have 3 in two monitors). Desktop background is freezed too. There is no any response to icons left click or right click. However, I can change from application (<Alt><Tab> or <Ctrl><F9>) or even change from desktop (<Ctrl><Fn>). Krunner works too (<Alt><F2>) but panels are unrenponsive at all.

A backtrace and a bug report there would be useful.
Thank you, but my report is from 2017 and no one, except you, ask me about the issue. It's a pity but is too late and I even forgot the bug.
So has it stopped happening, or are you still experiencing the bug?
I'm using OpenSUSE 15.2 nowadays, so Plasma and QT libraries are not the same, I can't reproduce the issue.
Thanks for the update; changing status.
