I have found a work-around effective even though the Compiz is running. The principle (for M$ Windows running in the seamless mode under VirtualBox):
"As long as you keep some M$ Windows application window open you can minimize and restore other Windows applications without any problems with their proper redrawing. " To reproduce that you may try and install e.g. the following little analog clock into your Windows virtual machine: http://www.gljakal.com/clock/index.php The clock will stay running and visible on the Gnome workspace where you have the seamless desktop. An all other apps windows will work right. Perhaps, this can also help to track where this bug has its cause. -- virtualbox does not redraw background in seamless/compiz mode https://bugs.launchpad.net/bugs/230811 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
