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 Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2107454 Title: GNOME Shell crashed with SIGABRT at clutter_actor_finalize: assertion failed: (priv->grabs == NULL) Status in Mutter: New Status in gnome-shell package in Ubuntu: Confirmed Bug description: Ubuntu version (24.04) Gnome 46.0 NVIDIA RTX 3060 NVIDIA driver version (550) --- ProblemType: Bug ApportVersion: 2.28.1-0ubuntu3.5 Architecture: amd64 CasperMD5CheckResult: unknown CurrentDesktop: ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 24.04 NonfreeKernelModules: nvidia_modeset nvidia Package: gnome-shell 46.0-0ubuntu6~24.04.8 PackageArchitecture: amd64 ProcEnviron: LANG=en_US.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color XDG_RUNTIME_DIR=<set> ProcVersionSignature: Ubuntu 6.11.0-21.21~24.04.1-generic 6.11.11 RelatedPackageVersions: mutter-common 46.2-1ubuntu0.24.04.7 Tags: noble Uname: Linux 6.11.0-21-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sudo users _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/2107454/+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
