I am running into what I believe is a similar problem. These flickering white lines on the front image in the chroma key. The lines often seem to somewhat take the shape of what is the background , they mave and shift and change when I try to analyze them, but they almost always come back. it also seems like these are generally in the whitest parts of the image. did you ever get down to the bottom of it?
