I have this problem as well. Virgin/Clean install of Eoan Desktop install in a KVM virtual machine. Install package cqrlog, which has a long startup time and usually causes the "not responding" dialog to raise, but can be dismissed.
Under Eoan, the "CQRLOG is not responding" dialog cannot be dismissed - both "Force Quit" and "Wait" are greyed out and cannot be selected. gnome-shell then runs to 100% cpu utilisation (one thread/core) and repeatedly logs: gnome-shell[4157]: JS ERROR: TypeError: null has no properties#012_addWindowEffect@resource:///org/gnome/shell/ui/closeDialog.js:74:13#012vfunc_show@resource:///org/gnome/shell/ui/closeDialog.js:145:9 in syslog. Killing gnome-shell clears the "not responding" dialog. Not this is a virgin install to debug this problem, no extensions or anything else installed (except mariadb-server and cqrlog). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1841774 Title: gnome-shell freezes and continuously logs "JS ERROR: TypeError: null has no properties" in _addWindowEffect from vfunc_show (both in closeDialog.js) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1841774/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
