Then again, now that I have seen your flickr pictures, I see you always have the same 0 angle. So my proposed explanation is not quite on point. But I do still believe this is an artifact of emulation rather than a bug, and for reasons similar to what I described. So try varying the vertical spacing and see how that affects the spurious thickening.
