           Summary: Accelerated canvas2D has bad clipping performance
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: ASSIGNED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: senorblanco at chromium.org


Since our Canvas2D path does not implement clipping, all draws are done in software and uploaded, which is mighty slow for sites with lots of clipped, composited objects.
