-- Information about the crash:
Hello,

After upgrading to the latest KDE in debian unstable (versions shows as kde-plasma-desktop 5:162, kwin-wayland 4:6.5.0-1), I have started getting a Kwin crash after unlocking the screen. It doesn't happen every time but firefox and jetbrains running programs crash.

I have recently rebooted after applying the updates. Let me know what else I can provide.

Thanks
Mike

The crash can be reproduced sometimes.
