--- Comment #4 from TraceyC <[email protected]> ---
We need to find out if kwin crashed or froze.

If it crashed, there will be a coredump and we need a backtrace of it so we can
figure out what's going on. If there is one, can you please attach a backtrace
of the crash using the coredumpctl command-line program, as detailed in
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl
?

Otherwise, can you check kwin's logs when the hard freeze occurs? 

  journalctl --boot --user-unit plasma-kwin_wayland > ~/log.txt

Also, is there any chance that you could retrieve kwin's backtrace when the
hard freeze occurs? You would need to ssh from another computer and attach a
debugger to kwin process, e.g.

  sudo gdb -p $(pidof kwin_wayland)

then type

  bt

and paste the output here. Thanks!
