Come to think of it, it's not CPU... when it happens (and I've noticed now that it's not just that song, but the Animaniacs one too) I can pause/unpause the music and it's quite responsive. I can even pop up emphatic's menu. If I just pick "On", it goes back to the custominfo screen without scrolling the lyrics. But instead, if I change the mode to horizontal, the lyrics scroll (over top the player's vis) immediately. I quickly changed back to custominfo and it scrolled right away (could'a been a coincidence, dunno).
