The page http://www.panic.com/blog/2010/05/vegan-co-op-luncheon/ has a randomly selected small rotation applied to a blog entry. When scrolling this on OS 10.5, there are very visible graphical smudges left behind. Forcing a full repaint (by resizing the window, for example) cleans up the smudges. I'll attach a screenshot. I don't see any issue on Safari 4.0.5 on Windows 7, but it looks like on that platform there's no attempt made to anti-alias the text. I haven't checked if this happens on 10.6.
