Just off the top of my head, I don't think this is a bug per se. I think it is an artifact of the smoothing (anti-aliasing) under emulation conditions. That is, since the emulator is emulating a phone screen with its own resolution, aspect ratio and pixel size, on a computer screen with different resolution, aspect ratio and pixel size, the calculations it performs when deciding to include a given pixel are going to be different than on the phone. So for lines at certain angles, this could mean including more pixels, giving the appearance of a wider width.
