           Summary: Coordinated Graphics : Reduce the number of messages
                    sent to UIProcess when creating  and deleting
                    compositing layers.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: seulgikim at company100.net


Currently, LayerTreeRenderer in UI Process creates a layer when CreateCompositingLayer message is received. When a lot of CreateCompositingLayer messages are sent in the same cycle, some layers are not created in the UIProcess, and causes crash when trying to use the omitted layers.
