--- Comment #20 from Henri Verbeet hverbeet@gmail.com 2013-02-25 12:00:39 CST --- Actually, I debugged this a while ago for CrossOver, and it's an OS X bug. It looks like some kind of broken optimization for fullscreen windows that copies the contents of the backbuffer to the frontbuffer without being asked to. Since we never draw to the (GL) backbuffer for a typical ddraw application, it just contains garbage, and that's what you're seeing. As a hack you could probably force a single buffered GL context for those applications, but that's not something we want in Wine.
