I can confirm that Benjamin has solved the issue for us with comment #89. I too was a user of the Workspace Grid extension. It doesn't start at all in Dingo, and is greyed out in gnome-tweaks. I removed the plugin through extensions.gnome.org and restarted, and now everything is working.
Thank you Benjamin, you have my heartfelt thanks. :) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
