           Summary: [Qt][WK2] Nested fixed elements scroll too fast
           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: yael.aharon at nokia.com


After http://trac.webkit.org/changeset/113791, the position of fixed elements is adjusted during scrolling to compensate for the difference between the scroll offset in the web process and the ui process.
Nested fixed elements are adjusted, but so are their ancestors, resulting in the delta being applied twice.

A patch is coming soon.
