The problem also occurs then attempting to display a sprite, but its black with some garbage pixels in it.
I have the font to index 999, to keep it out of the way. I don't actually use any sprites, but was making a capture at one point of the 3d and scaling it up, this resulted in all black, with white boxes for the text. With 3d drawing normal, it worked fine, except white boxes where font should be. I'm not use alphamode either, so I don't think that's the problem. I could just be because its an older G5 and the OS and drivers might be out of date. Anyone have an OSX system?
