Using an Adjustment Layer to distort underlying layers, e.g. Position and Skew (Screenshot 1), when rendered to RGBA with a Straight alpha, shows a strange behaviour in the RGB channels: both the original and the distorted underlying graphics are included (Screenshot 2). This seems like an unitented render behavior to me.

Screenshot 2 (showing RGB Straight. without Alpha Applied)
