missing window decorations in virtual desktop

When I set the size of the virtual desktop so that it matches my desktop
resolution (1440X900 in my case) then the opening movie as well as the main
menu of the game appears without window decorations/window borders.

This occurs since commit 790133e95036597092443b30c0fe0aa6a40a9167.

This commit has the side effect that the patch from Zhiyi Zhang which is
intended to fix bug #55810 simply doesn't work. Bug #55810#c14

To reproduce the problem in Celtic Kings demo:
1. set up a VD that matches your desktop resolution
2. run the demo
