Hey, I managed to find the SDDM bug causing the issues when logging out.
I created a pull request upstream: https://github.com/sddm/sddm/pull/2205 It fixes the bug entirely on my machine.The bug was because when logging out there can be a race condition where the new server socket of the SDDM daemon starts before the old server socket gets closed and deleted.
The fix will explicitly close the server socket before opening a new one. Regards.
