           Summary: XSLT mandelbrot slow and incorrect rendering
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
               URL: http://img.thedailywtf.com/images/200904/mandelbrot.xml
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: myrd at projectmagma.net


Go to URL to load XLST-based mandelbrot.xml.

Notice WebKit's performance - particularly the spinning beach-ball, long load
time, and lack of incremental rendering. The same page loads significantly
faster under Google Chrome on Windows. Try it.

It is also faster on Firefox Mac (but not as fast as Chrome).

On IE Windows and Opera (Mac/Windows) it updates incrementally - which looks
much better than a spinning beach-ball - and should be done on Safari if it's
taking so long to render.

Finally, the result rendered by Safari is incorrect. If you compare it to the
results in Google Chrome and IE on Windows, you can see that the right line
endings are all alines (so it's a rectangle). This is not the case under
Safari.

Finally, the colors do not match those shown in IE or Opera. But this may not
be a bug, since Chrome and Firefox show similar colors to WebKit.

Tested with WebKit nightly.



Now load the same page with IE under windows.
