I'm not sure about this.
I've tested this change in VMWare and I get quite a lot of "flashes" when 
the display is updated in quick succession. The flashes are really 
noticeable and are not there without the patch, so it looks as if the 
window buffer does help to stabilize display updates in D-I.
