I think it's very much a matter of resolution, different platforms have a different screen resolution. A lot of computer screens use 1600x900 (16:9) or 1600x1200 (4:3), for example. This is also mentioned on the help page on Creating the background skin, there is a dark grey area that will not appear on some screens. In this case, this could potentially be "fixed" by expanding the group of characters, but then you keep the same problem with other characters. You could change your screen resolution, but it might be better to leave it; a background is created for the community, and almost every other visiting user will not even notice that there is supposed to be more to the background.
