I must confess that I haven't read through the full history of this bug report, but I can confirm that it is still present in 12.04.1.
This happens when the full screen application on the second display is not focused. As long as the application still has focus, the top bar (and the rest of the Unity interface if you have opted to show it) will remain hidden, but when the application loses focus it is drawn on top of everything on the display. This is especially noticeable if you are running a presentation on the second display and need to keep another window focused on your main display, or if you (as in my case) are running a video on a connected TV set while using the computer for general browsing and bug reporting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/734908 Title: Unity is visible on top of fullscreen apps To manage notifications about this bug go to: https://bugs.launchpad.net/ayatana-design/+bug/734908/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
