I can't if I am kicked out to SDDM, right?
Comment 4 Matej Mrenica 2018-10-16 17:54:50 UTC 
Also to make matters even worse it looks like every app when maximizing crashes Plasma Wayland. That is at least for me.

Getting a backtrace on wayland is a bit hard. Easiest solution is to use
another machine, ssh in and run "sudo gdb --pid `pidof kwin_wayland`" then
typing "continue" reproducing the crash and typing "backtrace"

Alternatively coredumpctl can help

Meanwhile, I updated to qt 5.12-beta2 and it fixed my issue, so I am closing this.
