I have a render in image patch that sends an image with alpha to an NS imageVIew in IB. This works as expected on my ATI cards (1900,3870,4870) but on GMA 950 (plastic macbook, mac mini) the color and alpha display is incorrect. The render in image output is set to 32 bits. What appears in the gma displays looks like the result I get on the ati cards if I set the render in image output to 8 bits. Is this a driver bug or is there something I need to to do to the image view to get it to display correctly in all cases. I don't really understand setting the pixel format options or even where I would set them in this case. Anyone else notice this issue with gma 950?
