           Summary: Coordinated Graphics: remove redundant update of non
                    compositing layer.
           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: luxtella at company100.net


Currently, we update non compositing layer when the page scrolled. However, it
is not needed, because TiledBackingStore can scroll without tile update.
