I've had this happen a number of times again on a fresh 19.10 install, with no extra extensions enabled.
It seems to happen when an app isn't responding for a handful of seconds and trying to switch between apps via Alt+Tab or between workspaces. A SIGSTOP would probably be enough to simulate the app hanging. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1850615 Title: gnome-shell hardlocks under load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1850615/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
