After further testing I find the following in the logs at the approximate time of crash:
gnome-shell[4057]: Attempting to run a JS callback during garbage collection. This is most likely caused by destroying a Clutter actor or GTK widget with ::destroy signal connected, or using the destroy(), dispose(), or remove() vfuncs. Because it would crash the application, it has been blocked. Apr 20 09:37:27 gnome-shell[4057]: The offending callback was SourceFunc(). I have also seen a lot of these messages although it isn't clear to me if they are related: nome-shell[4057]: == Stack trace for context 0x5620be49a900 == gnome-shell[4057]: The offending callback was set_actor(), a vfunc. gnome-shell[4057]: Error adding children to desktop: Not enough place at monitor 0 gnome-shell[4057]: message repeated 49 times: [ Error adding children to desktop: Not enough place at monitor 0] Perhaps this will be helpful in finding the cause of the crash. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1181666 Title: gnome-shell randomly blocks mouse clicks from working in app windows To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1181666/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
