backtrace of kwin_wayland hanging
SUMMARY
On my laptop and desktop Plasma from git on Wayland hangs from time to time and
feel generally sluggish. It started a few days ago when rebuilding with
kdesrc-build.
The hangs are always reproducable when starting apps (around one second long
there) but sometimes also happen when using apps like Firefox or Dolphin, and
they can get quite long (like 30 seconds for example).
At the same time plasmashell is using a lot of CPU, and the app launcher shows
"applications updated" in a loop.
On X11 this problem is not as visible but also happening (as evident by
plasmashell using a lot of CPU).
The Wayland and X11 sessions from the Manjaro packages do not have this
problem.
