--- Comment #3 from Rico kgbricola@web.de 2009-04-01 13:07:23 --- Confirming. This problem happens with all OffscreenRenderingModes.
A workaround is to change in game to a higher resolution and then change in game to a lower one ( 1600x1200 -> 1280x1024 ). But if you restart the game you have to re-apply the workaround again.
