People can't see my skin because my username is too long. (Sounds weird, but true)

When I'm on certain servers, my friend, caboj8, says he can't see my skin, even though I can see it on me. I started typing to people asking if they can see my skin, but they tell me I look like Steve. I looked at some other people who have their names cut off like mine (probably because it is too long) and I can't see their skin either, they look like Steve. Everybody who has a short name has a custom skin, not sure if this has to do with anything, but maybe. Please Help if it is not a bug.
