I suspect that this problem is not with the server or site, but with the individual browser (maybe the encoding settings?). If it were the site code, wouldn't it appear for everyone all the time?
It only does it with long threads or if there is a long url in a post.

Look at this thread, make sure it's in threaded view, not flat.
