I can confirm the existence of this bug, also with a java application (Cameo System Modeler) when using Wayland. When I start the application it starts with a loading screen, and when it finishes with loading and wants to dispose the loading screen (probably a JFrame, ad Diego mentioned) I get a crash and Ubuntu logs out. I can reproduce this issue consistently.
Switching to X solves the problem, no more crash, I can use Cameo.

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 : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
