I checked it, the exactly same issue with a gnome system, without openbox. So it's not DE specific. Now it would be helpful to know if it's hardware specific, isn't it, but I have no chance to check this. If anyone is interested in space-shooter-MMOs try to get a closed beta key for the game and test it: http://blackprophecy.gamigo.com/ I've heard about other ways to optain a key, but I don't know anything about it.
