Hi, the "difference" blend mode is great to spot any differneces between 2 layers. Identical pixel blend to pure black, any difference are rendered to non-black, which can be amplified by a levels adjustment. Unfortunately, this will only work when alpha is 1 (pure white). Otherwise, he blend formula will lead to non-zero results for color and below-one results for alpha, making this useless for spoting differences. My question: Is this by design? To be useful for spotting differneces, i would expect it to deliver RGB=0 and alpha=1 if both layers have equal RGB and alpha va
