Still not entirely clear, but let me offer this and you can confirm if this is your problem.
(1) Open a terminal. (2) Maximize the terminal window using the "maximize" button or control-super-up key. (3) Make the terminal window fullscreen using the F11 key. (4) Do something in the terminal. (5) Un-fullscreen the terminal using the F11 key again. At this point the window controls normally present in a maximized window do not get drawn. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1249608 Title: When opening fullscreen windows, window buttons disappear To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1249608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
