Not sure what's going on here. I'm running an LWJGL app on a Mac mini (ATI Radeon 9200) and alpha blended colors are showing up posterized (too saturated, and split into bands). The same exact app looks fine on a Mac G4 laptop and all other computers I've run it on.
Here's a sample of what I'm talking about (top is wrong, bottom is right):
http://potatoland.org/images/mac_mini_posterize.pngThe two mac machines have identical settings: OS X 10.3, Java 1.4.2_05, display settings are the same (millions of colors). I'm running .95 though I don't think this is an LWJGL issue.
I'm guessing this has something to do with the card or some OpenGL tweak I need to do. Has anybody seen anything like this?
