Thank you for your bug report. Jojo: Please avoid overloading a bug report with more than one problem (in this case can't maximise/unmaximise is one bug, broken cube is another).
The cube problem is probably handled by bug #82957 ... -- desktop effects not working properly under Intel Mobile 915 https://launchpad.net/bugs/92043 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
