I've noticed that when I set NSOpenGLPFAColorSize to 64 in my project (after making sure the app is runing on capible hardware like the recent iMacs), that something is dithering my colors before it gets to the screen.
This is understandable in most cases, as the display is only 30 bit and I'm handing it 64 bit color- but in my case, I'm filling a box with a solid color, and the box is being dithered when there's no reason for this to happen.
Is there anyway to tell OpenGL to stop dithering, and just try and round the color values in a consistent manner? Setting my color size back to 32 works, but that's not good for my app.
