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.
Stack trace of thread 24151:
#0 0x00007f3ce3235a00 n/a (n/a)
Process 25032 (jetbrains-toolb) of user 1000 dumped core.

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