Hi, hoping someone can help out here. I am having some issue with slab compositing. The patch below illustrates my issue - some composite .jxs work fine (such as average and normal and others) while others like additive, subtractive and others, don't. On my machine it ends up looking like a colormode issue, but I cant seem to get it right. It will work with both sources as ARGB, but not with both sources as UYVY.
I've distilled a much larger patch down to what you see below. Im running a MacBookPro i7 / OS 10.6.4 / NVIDIA330M 512
