After resume from suspend some transparent egdes persist on screen

[Bartosz Woronicz]

Some graphics artifact persist after resuming from suspend. The virtualbox windows was not visible. I could only click on the bar above and close the VM, when I started again it worked, but I needed to kill the X to fix the graphical artifact like in screenshot ("The visual issue" attachment")
