           Summary: Hangs when navigating page laden with large animated
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
               URL: http://www.neogaf.com/forum/showthread.php?t=355837
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: cabel at panic.com

When scrolling through a page with a lot of large, many-frame animated .gif's,
latest WebKit nightly (and Safari 4 Beta) will to hang / freeze for a while.

Steps to Reproduce:
1. Load the URL.
2. As the page loads, use the Page Up / Page Down keys or mouse to scroll
through the page.
3. Most importantly, scroll to the bottom of the document, gradually. Then try
scrolling back up.

What's Expected:
Scrolls like butter.

What's Happening:
As the page approaches / reveals post #39, which contains a repost of a large
animated .GIF, the browser will begin to stutter.
The spinning cursor will appear for seconds at a time, and appear to freeze.
Eventually it might un-freeze, only to re-freeze later.
In short, the browser becomes unresponsive.
