           Summary: Movement of objects is very stuttering
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jurekraben at googlemail.com


The movement of any kind of objects is very stuttering in this new html5/canvas/webgl benchmark:

http://peacekeeper.futuremark.com

All animation will not run smoothly with 60 frames / sec. See Chromium for a _lot_ better result.

In my opinion this behaviour was introduced with Safari 5.11, because of the separation of "web content" and Safari windows itself in different processes. A lot of HTML5 webpages do not animate smoothly anymore with Safari 5.11+ and recent Webkit.

Please fix it. It looks really ugly. Thanks.
