--- Comment #7 from Henri Verbeet hverbeet@gmail.com --- Thanks. The issue seems to be the game doing a (scaled) blit to a multisampled render target, at least for the GL errors. Does it work any better if you disable multisampling, either in the game settings or with the "Multisampling" registry key? (See also http://wiki.winehq.org/UsefulRegistryKeys)
