Window decorations (title bar, borders) are missing when certain full-screen
games/apps are running in virtual desktop mode.

One example is Crystal Cubes (a small, freeware Tetris clone, download link
added to url):
1. Create a new wineprefix, set a virtual desktop sized to 1024x768.
2. Install the game, use winetricks to install native d3dx9_36.dll
3. Start the game (by default it is running in full-screen mode) and see that
window decorations are missing.

I tested on Fedora 16 + Gnome (with or without compositing).

This is due to the following commit:
