I have mutter from proposed, and I don't see any newer version of gnome- shell in the proposed repository.
I've attached the crash file as well. Also, I'm not really sure if the crash I reproduced is about this bug or not. I've had other crashes that were filed separately and have different stack traces but were caused by using the touchscreen also, such as https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1861542 Just in case, here's the actual versions: sibrus@poseidon:~/tmp$ dpkg --list | grep mutter ii gir1.2-mutter-6:amd64 3.36.3-0ubuntu0.20.04.1 amd64 GObject introspection data for Mutter ii libmutter-6-0:amd64 3.36.3-0ubuntu0.20.04.1 amd64 window manager library from the Mutter window manager ii mutter 3.36.4-0ubuntu0.20.04.1 amd64 Example window manager using GNOME's window manager library ii mutter-common 3.36.4-0ubuntu0.20.04.1 all shared files for the Mutter window manager sibrus@poseidon:~/tmp$ dpkg --list | grep gnome-shell ii chrome-gnome-shell 10.1-5 all GNOME Shell extensions integration for web browsers ii gnome-shell 3.36.3-1ubuntu1~20.04.2 amd64 graphical shell for the GNOME desktop ii gnome-shell-common 3.36.3-1ubuntu1~20.04.2 all common files for the GNOME graphical shell ** Attachment added: "_usr_bin_gnome-shell.1000.crash" https://bugs.launchpad.net/ubuntu/focal/+source/mutter/+bug/1870867/+attachment/5395779/+files/_usr_bin_gnome-shell.1000.crash -- 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/1870867 Title: gnome-shell crashed with SIGABRT meta_x11_get_stage_window: assertion failed: (META_IS_STAGE_X11 (impl)) To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1870867/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
