When your system freezes, could you try pressing alt+sysrq (or
alt+printscreen), and then ctrl+alt+f4 to switch to a virtual terminal?
If you can do that, could you first run htop to check the CPU usage of kwin?
Then, could you run attach gdb to the running kwin process (gdb kwin_wayland -p
(pid of kwin_wayland process)), hit ctrl-c, and provide the output of bt?
(debug symbols needed,

I was able to reproduce by moving a window along top edge back and forth, and
saw kwin stuck in updateInteractiveMoveResize in window.cpp. So this very
likely has same underlying cause as BUG 481610
