@TomC, it's not just "loading" if that's what you're asking. There seems to be something wrong with the graphic, which looks to me like a blown-up pixelated version rather than a full-sized version rendering properly. Either that or it's freezing on the "loading" part.
@New Boy, it happens only on that screen; the avatars on every other page (including the profile page, where the avatar is actually bigger) look fine. Also my connection is not slow.
