I experienced this problem today on 23.04 with latest (production) updates.
The tags on this bug appear to say it was fixed in mutter "44.1" however fully updated 23.04 systems still have mutter 44.0: # apt list --installed | grep -i mutter gir1.2-mutter-12/lunar,now 44.0-2ubuntu4 amd64 [installed,automatic] libmutter-12-0/lunar,now 44.0-2ubuntu4 amd64 [installed,automatic] mutter-common-bin/lunar,now 44.0-2ubuntu4 amd64 [installed,automatic] mutter-common/lunar,lunar,now 44.0-2ubuntu4 all [installed,automatic] The problem is severe, as it causes Gnome to immediately exit and kill all my processes (losing work). 2023-05-09T20:32:12.869757+12:00 gnome-shell[292332]: libmutter:ERROR:../src/core/window.c:1533:meta_window_unmanage: assertion failed: (window->display->focus_window != window) 2023-05-09T20:32:12.869780+12:00 gnome-shell[292332]: Bail out! libmutter:ERROR:../src/core/window.c:1533:meta_window_unmanage: assertion failed: (window->display->focus_window != window) 2023-05-09T20:32:12.869794+12:00 gnome-shell[292332]: GNOME Shell crashed with signal 6 In my case the problem was triggered by running the latest version of OWASP ZAP (2.12) running with openjdk-21-jre.

Setup: Ubuntu 23.04 Ryzen 6000 AMD 680 Gnome 44 Sweethome 3D 7.0.2 (from the repositories) Whenever I load a file in Sweethome 3D my desktop session is killed instantly. I am either thrown back to the desktop login or it stays black. This seems like a severe problem to me. Under no circumstances should an app like Sweethome 3D be able to crash mutter. I don't know how to give any logs. But I attach a sample file for Sweethome 3D. Actually it crashes with any file. Steps to reproduce: Start Sweethome 3D Draw some walls to make Draw a room Save to file Quit Sweethome 3D Start Sweethome 3D Load the file Crash To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/2016308/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
