Invert colors snapshot method sometimes produces flipped image

@joshmsamuels I have a theory what's happening here, but I can't get it to reproduce locally right now. Can you try making this change locally and let me know which path it's taking (is the image backed by a CIImage or CGImage)?

I am getting the else case locally. Is that the expected behaviour?
