Description Fabian Vogt 2016-09-28 19:27:07 UTC 
When moving a window, sometimes kwin_wayland crashes with a stack overflow:

Reproducible: Always
Comment 1 Martin Flöser 2016-10-04 07:56:28 UTC 
looks like it cannot find a cursor theme.
Comment 2 Martin Flöser 2017-10-04 19:21:48 UTC 
Setting to needsinfo/backtrace as I cannot really see where the problem would be in the code.
Comment 3 Fabian Vogt 2017-10-04 20:03:47 UTC 
I haven't seen that crash in a while, so I'll be optimistic and say that it fixed itself somehow...
