I'm really thinking this is an xorg problem as it affects Unity 2D as well. Something is really wonky and looks like your binding box for mouse movement is too short on the left (maybe even the right.)
In the meantime, you could try 'sudo dpkg-reconfigure xserver-xorg' in a terminal, rebooting, and seeing if that works. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/965643 Title: Unity 5.8: auto-hide using mouse reveals launcher inconsistently To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/965643/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
