I have found that if you stop or skip to the next song while the currently playing son is
A) At the end of a pop hits monthly and the ending credits are still sliding in from the side.
B) Just started some of the All Hits songs that have the funky little Marquee scrolling up from the bottom.
C) Tried to play a corrupted kma
D) Who knows what else might cause this.
The work around that has worked for me everytime (although now I know what to avoid to avoid this problem) is to take one of those All Hit songs (I use "You Oughta Know") and keep it at the top of your playlist, when the graphics scramble all you need to do is play the opening untill the graphics come up completely and the little lights start blinking. That should fix it, it does my shuttle with Nvidea graphics.
Just for fun before/after your show you can make this happen by doing the afforemention A or B and then try the fix to make sure it will work for you.

According to MTU's versions page this was a problem that's been fixed in the upgrade.
Hope this helps.
