So I upgraded to 4.2.1 and JB with GP(rc2) and since I"ve noticed that when playing music, and the screen powers off, when it comes back on, the cover art is not showing. The song title and album are on the home screen, but no cover art. I've tried it with several mp3s, and resynced songs. I should note that I'm using pwntunes, but in the cover flow the artwork is present.

any thoughts? no themes enabled, all winterboard options disabled.... 3gs, running 4.2.1.
