I believe there is a workaround, for those who haven't read the comments in Bug 1053895 or Bug 1063690
The problem started when "Unredirect Fullscreen Windows" became the default (bug 1063690), and the problem goes away when "Unredirect Fullscreen Windows" is unchecked. You can either turn off "Unredirect Fullscreen" at this location: CompizConfig Settings Manager -> Composite -> Unredirect Fullscreen Windows Or you can "blacklist" Virtualbox by adding to the string in "Unredirected Match" (Click the "Plus" symbol, click "Grab", click on the Virtualbox Window, check "Invert" and click "Add"). It should add something like this: " & !(class=Virtualbox)" to the end of the string. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1096314 Title: Minimizing full screen Virtualbox re-draws full screen with Virtualbox image To manage notifications about this bug go to: https://bugs.launchpad.net/virtualbox/+bug/1096314/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
