            Bug ID: 172626
           Summary: [iOS] Disbale Async image decoding when synchronously
                    painting a newly parented WebView
           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

When brining a WebView to the foreground we have to draw the page synchronously so the user does not see empty rectangles in the window. This means the large images has to be synchronously decoded as well so the user does not see flashes in the page because the images are not ready to paint.
