I saw the same thing on a Feisty install inside VirtualBox. Another problem I have is that the mouse cursor should be white, with a black border. When moving the mouse to the top of a frame, it changes into a resize cursor, which is white with a purple / pink border. All other resize cursors look fine.
Unfortunatly I can't take a screenshot, because there it looks fine. -- Ubuntulooks theme corruption in VirtualBox https://launchpad.net/bugs/84317 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
