            Bug ID: 218871
           Summary: [GPU Process] Rendering PDFDocumentImage is broken
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Canvas
          Assignee: webkit-unassigned at lists.webkit.org

Open the attached test case.

Result: WebKit crashes with the calls stack below.

Note: Currently we do not record drawing the PDFDocumentImage. We need to ensure that drawing the PDFDocumentImage to a the ImageBuffer happens in the GPU Process.
