Virtualbox should ask the guest to totally redraw the screen when restoring it

Description (last modified by frank) (diff)

I'm using VirtualBox in fullscreen on my linux host (running compiz). My guest is another linux distro running compiz (unity, in fact).

Consider this scenario: I loaded my guest in fullscreen and after some time, I've minimized the fullscreen guest window. Now, all the times I want to switch from the host screen to the guest screen, if nothing is moving there, I've to move something inside the guest to make it to redraw the screen completely. Otherwise it will draw (and show) only the few pixels that are changing.

To test this for example, before minimizing the guest, you can leave there a restored terminal running a script like "while (true); do echo "Test" && sleep 5; done". When you'll maximize the guest window again only the terminal pixels really changed will update on your screen.

So, I guess that when the VBox window has been remapped the host, through the guest additions, should ask to the guest to completely redraw the screen and not only the updated pixels.
