Some updates here: The shell isn't really hanging... The fact is that the input/output GLib Sources that the shell adds to the main context are starving and never processed because we add thousands of timeouts and `Meta.Later` sources as per a `window-removed` signal that is triggered thousand times (source is actually `[gnome-shell] this._queueCheckWorkspaces`).
This leads to CPU being 100% spending time in processing such sources (https://usercontent.irccloud-cdn.com/file/v1ZGs5f6/image.png) thousands of GSources being added: https://i.imgur.com/QUuuZA1.png And these are added via https://usercontent.irccloud- cdn.com/file/V4jfRY94/with%20laters%20added%20at that sends the window- removed signal (https://i.imgur.com/PNBn6Cv.png). Now, it seems possible that the fixes part of 42.2 in https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2413 fix this case. But we still need to test that. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1976204 Title: system freeze and gnome-shell reports multiple stack trace To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1976204/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
