When the system is idle, the wayland compositor crashes and takes down all applications with it. This happens very often and makes wayland unusable since 5.27.x. The bug is NOT reproducible on 5.26.x. Logs show a lot of the following sort of error: "Mar 28 13:00:25 Lenovo kwalletd5[643]: The Wayland connection broke. Did the Wayland compositor die?" Perhaps relatedly, I also have several of the following errors: "Mar 28 12:53:02 Lenovo kwalletd5[643]: qt.qpa.wayland: Creating a fake screen in order for Qt not to crash" Here is the systemd coredump from the logs: 3/28/23 1:00 PM systemd-coredump Process 667 (kwin_wayland) of user 1000 dumped core.
