Thanks for all your help.

The red (supposed to be orange) rectangle has to have that notch in it, so the yellow triangle can move to fit into it, so I can’t follow your first suggestion.

If I combine the red rectangle precomp and the triangle shape into another precomp, the behavior goes away, which might be the fastest solution.

Your second suggestion: if I use the Simple Choker effect on the triangle shape in the rectangle precomp, I shrink the size of the notch slightly, and this hides the behavior. Is that what you meant by “expand the lower shape”?

Thanks for your time.

Thanks for your reply.

Using Draft quality: does that mean that I can’t get this behavior to go away and still have a smooth-edged, antialiased triangle?

If I keep the layers in Best quality, I know that in the main comp, I could just move the yellow triangle down a pixel or two, and it would cover up the green. But this seems like an extra step I shouldn’t have to take.

Also, why does this blending of the values only happen on the right side of the triangle, and not the left? The green on the right side is from a shape layer, the green on the left is from the comp’s background color. How does that account for the different behaviors?
