           Summary: Paint very slow when horizontally resizing
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jamesr at google.com


When viewing the page: http://www.apple.com/safari/features.html vertical
resizes are taking a very long time (500ms+, sometimes multiple seconds) which
causes the entire browser to seize up, the window to go white, etc.  

Instrumentation points to the time being spent in ScrollView::paint() and
children.  Layout time is very very short, it appears there's something
horrible going on in the rasterizing code.

This behavior appears on the Windows and Mac WebKit nightlies, Safari 4 beta on
Windows and Mac, and in the Chromium port.
