           Summary: Insufficient viewport repaints when
                    FrameView::paintsEntireContents
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: allan.jensen at digia.com


If FrameView::paintsEntireContents is true, and the frameView is resized, the repaints emitted by the render-tree are wrongly limited to the frameRect. It appears to be because the visualOverflow of a renderview is equal frameRect. Since paints to contents implies no clipping or only clipping to total contents, the visualOverflow of RenderView should match the layoutOverflow.
