Although the original bug has been fixed, the screen blinks terribly if the window is not active. The path is:
Open Windows 7 guest system in VirtualBox, full screen, on the right monitor.
It displays correctly in full screen mode.
Click anywhere on the LEFT screen, e.g. in Firefox.
Each time you move your mouse, or press a keyboard button, areas of the screen in the right monitor flicker.
