           Summary: When the scroller style is changed via delegate
                    method, the page needs a full relayout and repaint
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: bdakin at apple.com


In the delegate method updateScrollerStyleForNewRecommendedScrollerStyle (which is is ScrollAnimatorMac), to avoid paint artifacts when the styles switch, we need a full relayout and repaint. Since this is an uncommon operation, I think the easiest way to do this with certainty is to just reload the page in this case. Patch forthcoming.
