setContentOffset:animated: shows view background

Question

Hi,

I have a UIScrollView with with different view controllers for each page inside it. When I use setContentOffset:animated: to scroll to a different page I can see a white line between the pages. This white line doesn't appear when I scroll by dragging the UIScrollView.

Has anyone seen this problem before? Any idea of what I might be doing wrong?

Thanks!

Setting all of your backgrounds (as in all layers deep) to magenta is a good test, but you may find that doesn't help. I have the same bug, but everything I have is black. The white line is there scrolling some directions.
