I don't know how to reproduce this bug, but it seems coming after play games who needs a huge amount of graphic power or if I'm working on a lot of open windows. I have this bug with "nouveau" driver or "nividia" driver.
When it happens, i do a: compiz --replace and everything come back to normal. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/735162 Title: menu application appears behind window application -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
