I have this issue and the avatar pics for members are choppy or I can only see a portion of the top of the picture. When I switched over to the IP.Bored version I can see more of the user posted pics, but some are still cut out (the random ones that are cut out may have something to do with my browser at work more than anything).
Now, other computers... and this isn't an issue, so I don't know how helpful that was.
