Hi, I get the same bug, and it's triggered several times a day for me. The easiest way to trigger it it is use zoom, and start to move its window.
Here's the syslog: 2025-06-27T18:40:09.955623+01:00 XX gnome-shell[599549]: ** 2025-06-27T18:40:09.955820+01:00 XX gnome-shell[599549]: Clutter:ERROR:../clutter/clutter/clutter-actor.c:5353:clutter_actor_finalize: assertion failed: (priv->grabs == NULL) 2025-06-27T18:40:09.955849+01:00 XX gnome-shell[599549]: Bail out!

() Just as the original poster, I use ubuntu 24.04, and I use nvidia drivers (I'm using X11). I am happy to do more debugging if it would help to fix it. The bug extremely annoying, as all the windows are killed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2107454 Title: GNOME Shell crashed with SIGABRT at clutter_actor_finalize: assertion failed: (priv->grabs == NULL) To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/2107454/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
