--- Comment #62 from haarp liquitsnake@gmx.net 2008-03-23 11:29:15 --- Setting OffscreenRenderingMode to fbo (see http://wiki.winehq.org/UsefulRegistryKeys) seems to eliminate those brown shadows (among other things) and also the cause for the crash. At least as far as I tested, it doesn't crash with fbo.
