Scrolling down various pages (e.g. http://weblog.infoworld.com/yager/archives/2008/07/apples_iphone_c.html) causes the text to only be partially drawn correctly, with large blocks of white/black areas drawn instead, sometimes with a block of corrupted pixels between the good text and the blank bits. Scrolling back up causes some extra redrawing, but still partial text.

Reproducible: Always

Steps to Reproduce:
1. Go to http://weblog.infoworld.com/yager/archives/2008/07/apples_iphone_c.html
2. Scroll down page (mouse drag on scrollbar works best), noting main text becoming blank a little after "From Section 3, Confidentiality:"
3. Scroll back up, seeing partial redraw of previously blank sections.
Actual Results:  
Partially blank text.

Expected Results:  
The full text being properly drawn!

Appears to now be fixed with build id 20090319030732. Site still feels slow, but no permanent visual corruption.
