Description Ralf Jung 2022-09-22 16:38:57 UTC 
SUMMARY

I was dragging the main Zoom window to another screen when zoom also opened a notification window telling me about who is the host or something like that, when kwin froze entirely -- I could still move my cursor but no interaction with the system was possible. I had to 'killall -9' kwin to be able to use my system again.

ADDITIONAL INFORMATION
Comment 1 Vlad Zahorodnii 2026-01-22 11:53:39 UTC 
Interactive move code used to have a code path where kwin could get stuck in an infinite loop, that code had been rewritten a while ago so there is no a while (true) loop.
