I am running the Ubuntu Gnome 3.20 PPA with Ubuntu-Gnome 16.04 and am still experiencing this issue.
I do not use virtual desktops / workspaces. I just used tweak tool and set my workspace count to static and 1 to see if this helps based on Axel's comment. I am not running the nvidia graphics driver, I have a build in 3rd gen Intel so i915 driver I think (built in to kernel) so I don't think Axel's nvidia driver is at fault. -- 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 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
