[Webkit-unassigned] [Bug 76689] New: CSS Shaders: Repainting the FECustomFilter requires full source image

https://bugs.webkit.org/show_bug.cgi?id=76689

           Summary: CSS Shaders: Repainting the FECustomFilter requires
                    full source image
           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: achicu at adobe.com


Because the shader has access to the whole image, repainting a filter chain with a FECustomFilter needs to paint the whole RenderLayer instead of just the dirty areas.
