I'm also getting this bug on Precise. This is very reproducible with applications set to start on login, like alarm-clock-applet. The top panel obscures the titlebar for the window, making an Alt+drag necessary to drag the window out; the window is impossible to close if you don't know keyboard shortcuts for window management.
Also, if the launcher is set to its default of being always visible, the window(s) will appear underneath that, as well, which just looks weird. ** Tags added: precise -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/861879 Title: restarting unity causes that window top bar is under top panel To manage notifications about this bug go to: https://bugs.launchpad.net/compiz-core/+bug/861879/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
