Description mitz 2006-10-29 16:12:47 PST 
Fixed boxes aren't treated as such for repaint rect calculation, so if the document is scrolled, they don't repaint properly. See attached test case.

I'll try to narrow down the revision range later, but this regression is probably from the change that rendered "fixed" parameter to computeAbsoluteRepaintRect() useless.
