Weird that affects the yellow (R+G) channel but not the blue; and sadly, no it doesn't affect my problem despite being commented as related to color type 2.
An annoying thing here is that I had to look into this code several years ago and I have horrible memories bubbling up about how painful it all was. I really hope it isn't a change I made that is the problem...
