I don't see the picture of understand what wireframe would have to to with the bug, but I see it too... an not in wireframe.
The starfish is blocked out by it's own shadow on the glass. You can see the tips of it's arms peeking around the shadow, but otherwize it's invisible if it's on the glass. The shadow is pretty much transparent to everything but the starfish which it hides completely... very bizarre. Luckily it's almost impossible to get the starfish up there, especially in screensaver mode, but I'd like to keep him up in the glass all the time AND be able to see him!
