Front Row: Long load times and scrolling problems

Front Row takes a long time to load lists of artists/albums/etc and frequently jumps back while scrolling down through the list once it has finally loaded. This started happening a couple of months ago, and the only information I've been able to find online is that a few forum posts have been made by others with the same problem, to no avail.

Any idea what causes this and what I can do to fix it?
