The stack trace is a little different. It will be interesting to see if we have anything like the same quantity of this crash as bug 1877075.
I think crashes like this can still happen if a graphics driver or gnome-shell extension is making Xlib calls from a thread. We won't get away from that until/unless we find the offending thread. And the offending call might have happened a little earlier than the actual crash (which seems to be in the correct main thread). We should keep an eye on this to see if it is specific to some extension, or maybe to some specific graphics driver. -- 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/1886059 Title: gnome-shell crashed with assertion failure "!xcb_xlib_threads_sequence_lost" [xcb_io.c:260] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1886059/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
