------- Additional Comments From willie@froq.net 2006-02-10 11:51 ------- I'm not sure, but I've tested a few OpenGL demos recently (stuff that used to work a few months ago), they seem to expose similar behaviour now. Those demos seem to use a partially transparent overlay to simulate a grain effect, and only this overlay is visible with recent Wine releases - everything "behind" the overlay is just black/ invisible. Might be the same bug?
