Reading this (although long) might help you get a better understanding:

At least the "Mist Cave" in the bottom right indicates to me that you made the "b" slightly wider, even if you didn't go beyond the original boundary of the pixel size. It's now sampling from the "b", which is why you get that line - at least, that's my guess. But, I'm not sure about the "e" or "u".
