i just upgraded a fedora 32 guest to fedora 33. the v32 guest was working flawlessly. the in-place upgrade was smooth. but the v33 guest is a *disaster*. so many KDE programs fail or crash it is hard to decide what to report and to whom to report it. it appears to be running plasma v5.19. anyone else run into this problem? i tried a gnome session but didn't push it very hard. i didn't see any problems though.

Moderator: Thread moved to the Linux guest area.
an update - upgrade to KDE 5.20 (it can be obtained from COPR) and turning off graphics acceleration for the instance in workstation avoids the problems and restores sanity.
