[Bug]: ramdom crash on KDE PLASMA 5.27 wayland, every opened programs will be closed, and back to a clean plasma desktop

[kamikaze211]

Summary

I have tested other kwin tiling scripts on KDE PLASMA wayland, but KDE didn't crash.
Also tested bismuth on X11, and never crashed.
Also tested on KDE-UNSTABLE(arch), KDE PLASMA 6 RC1 wayland, since all kwin scripts are broken on it, so nothing happened.
But only on wayland, when using bismuth, the KDE will restart, and back to a normal clean desktop(without any autostart programs, and no need to relogin to KDE, but everything opened will be closed.)
I don't know what log can I provide, but you can tell me, I will try.

PS: the package I installed from AUR also contains a wayland patch, seems to be this: #490

Steps to Reproduce

Since it happens ramdomly, so I cannot say how to reproduce it.

Expected behavior

I think it must be the same as on X11.

Sorry, it is not bismuth that make kwin crash.
I'm now using polonium, and kwin crashed again.

After some debug, it seems to be a qt5 bug/issue.
It may be fixed on qt6.
