------- Additional Comments From wine@roosch.nl 2007-15-02 16:17 ------- Ah, so the sky overhang should be a separate bug? Because that one is definitely a matter of some ground visibility-overlay-texture (I don't know what it should be called) being mapped upside down. It's the cause of the anomaly in the image that is attached to this bug. Mapping it correctly will also surely make the ground appear normally. And I don't think it is a matter of setting the offscreen rendering mode correctly, because that won't change the way that this specific texture is drawn (right?).
But if it should be a separate bug, just let me know. Also if I can help, I'll do what I can. (I've got pretty new hardware, so testing some stuf won't be a problem)
Cheers,
