I also have a similar issue, however it seems to be only triggered when using Telerik Fiddler (a Mono app, which is in beta for Linux). I assume there is a bug in Fiddler, but it shouldn't make the mouse unresponsive for the whole system.
When the issue occurs, the mouse is unresponsive though the wave animation when pushing it to the corner is rendered. The overview is not triggered via mouse though, but I can open it with the keyboard. Keyboard shortcut for Run (Alt+F2) does not work in that case but otherwise the keyboard appears to be working properly. Following the comments in this thread, I managed to switch to a terminal and restart gnome-shell, which fixed the issue (though Fiddler's window remained frozen). -- 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 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
