           Summary: [Qt] Very jerky scrolling because of blocking in tiled
                    backing store.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: Qt
          Severity: Normal
          Priority: P3
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ostapenko.viatcheslav at nokia.com


Scrolling is jerky when webkit tiled backing store is enabled because of long update of big backing store.
Noticeable even on PC with large window sizes, but quite bad on mobile.
Good test website is http://dpreview.com, but any heavy website with big amount of images will show the problem.
