Well, the big change in 3.5 is that it can call your callback much more
often than before. In particular it calls it to highlight and unhighlight
the selected item, compared to pre-3.5 where the OS would just invert the
pixels on screen. Are you sure your callback handles this correctly? Does
it make any assumptions about the draw calls coming in top-to-bottom row
order? That would not be a safe assumption.
(Just a few guesses.)
