            Bug ID: 173298
           Summary: Disable asynchronous image for server push and
                    streaming over HTTP contents
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Images
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: sabouhallawa at apple.com

For webcam pages, the MIME type is "multipart/x-mixed-replace". For this page, the server will push new data when it is available to the client. For the webcam case, new CachedImage and BitmapImage are created for the new image encoded data. If the BitmapImage is displayed asynchronously, there will a flickering between displaying the old and the new BitmapImage. Therefore, asynchronous image decoding has to be disabled in this case.
