--- Comment #10 from Dennis Schridde devurandom@gmx.net --- (In reply to Mike Lothian from comment #3)
I think this might be a duplicate of Bug 104762, which is fixed in master
Does deleting the shader caches work around the issue for you?
I tried: rm -fr ~/.cache/mesa
But that still does not allow me to start e.g. KRunner or KMail.
I managed to restart KWin from a VT, though, so that one might be affected in a different way.
Sadly the stacktraces of KWin and JetBrains toolbox are not as helpful as that of KRunner:
Process 24151 (kwin_x11) of user 1000 dumped core.

I will rebuild KWin with debug symbols and try to repro afterwards, to get a better stack trace.
