I had some problems after an update (krunner didn't work and kickoff search didn't either). I thought I had messed up things (had other problems not related to KDE) so I made a fresh install of the whole system, installing only KDE and Cinnamon as environments.
The problem with KDE is still there and I've got a new one.
Now I also have problems when connecting my laptop to a screen with HDMI, resulting in random disappearance of the main panel. I never had problems with the displays before, and had one problem with krunner in the past that was solved by reinstalling KDE.
Shall I just wait for further updates or there's something I can do to get my menus back?
