After triggering the bug, if I restart nested kwin_wayland, the xwayland windows start receiving input again -- they receive input as long as the nested instance is kept open. This seems to suggest that the issue may be in code executed when kwin_wayland exits.

fwiw I tried bisecting and I went all the way back to kwin commit 53a61dfac089626f45c483dce94fc7d6a8f58336 in March, and the issue still occurs. Maybe the underlying issue is in some other component?

Comment 3 Vlad Zahorodnii 2024-08-15 14:00:56 UTC

I cannot reproduce it

Comment 4 David Edmundson 2024-08-15 14:01:00 UTC

Can you check if you have any window rules set on the nested kwin_wayland?

I don't have any window rules set.

Does this still happen for you in Plasma 6.4?

If yes, does it also happen with a new user?
