Unfortunately the backtrace is lacking debug symbols. Due to that we are unable to investigate. If you are able to reproduce please attach a new backtrace with full debug symbols.

Hm, issue is that there are no debug symbols in repo. The is a qt-debug but kwin is not there and building kwin is quite a pain. The is a kwin-git in aur however i would guess that i need everything in git then not just kwin and it's make depends?

Or do you know any repo from KDE that supplies with debug symbols for Arch?
