           Summary: [chromium] Layout Test
                    compositing/geometry/clipped-video-controller.html is
                    flaky on Win/Linux
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: adamk at chromium.org

The following layout test is flaky on Chromium Linux and Windows.

compositing/geometry/clipped-video-controller.html

Flakiness dashboard:

http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=compositing%2Fgeometry%2Fclipped-video-controller.html

The diff is a single pixel of scrollheight:

-layer at (20,50) size 70x70 clip at (30,60) size 50x50 scrollWidth 352 scrollHeight 293
+layer at (20,50) size 70x70 clip at (30,60) size 50x50 scrollWidth 352 scrollHeight 292

There doesn't seem to be any culprit on the WebKit side. In Chromium, the timing lined up with http://src.chromium.org/viewvc/chrome?view=rev&revision=110733 (and thus I've CCed vrk at chromium.org), but the test doesn't seem to have anything in particular to do with the canplaythrough event.  James mentioned on IRC that this failure might be due to timing, so I've CCed him as well in case he has further thoughts.
