Lion - CopiesOnScroll Bug with table view



I have an NSTableView in a scrollview, and on Lion it's now smearing all of the drawing when scrolling:

Some things to note:


A) This doesn't happen on Snow Leopard
B) Yes, I am using a custom cell in the table view, but using a standard NSTextFieldCell has the same problem
C) [[tableView enclosingScrollView] setCopiesOnScroll:NO]  "fixes" it
D) copiesOnScroll is YES on Snow Leopard
E) For some reason it seems to only happen when scrolling new rows in from the top (scrolling up)


Any ideas? I'm really stumped on why this is broken all of a sudden.
