------- Comment #2 from mitz at webkit.org  2006-11-30 11:58 PDT -------
A huge part of the page is constantly repainting at 10fps due to one or two
elements having a small animated gif as their non-repeating background image.
Something like:
<div style="height: 500px; background:
url(http://www.wowhead.com/images/loading2.gif) no-repeat"></div>
causes the entire div to repaint on each animation frame. Note that the
background is non-repeating, so there's no reason to repaint the whole area.
Shipping Safari repaints only the 16x16 area that animates.
