That seems to be an anti-aliasing artifact. Some anti-aliased pixels are bleeding out the clipping box I drew over the image to hide the ugly parts :-) I guess I could try moving the clipping box so that it is exactly pixel-aligned, but I don't know if it'll matter that much.
Edit: Just checked, it is a small rounding error that makes semi-transparent pixels to blend with the background. The image is 0.433 pixels off-center both horizontally and vertically.
I miss the show so much
