Flakiness dashboard: http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=compositing%2Foverflow%2Foverflow-positioning.html Blame list for first failures: http://trac.webkit.org/log/?verbose=on&rev=116242&stop_rev=116240
This also happens to compositing/overflow/scrollbar-painting.html: http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=compositing%2Foverflow%2Fscrollbar-painting.html
Added compositing/reflections/masked-reflection-on-composited.html = PASS TIMEOUT compositing/visibility/visibility-simple-webgl-layer.html = PASS TIMEOUT somehow, they're popping one by one :)
compositing/overflow/overflow-positioning.html just uses two timeouts. If this is really timing out, then it indicates some serious issue with the testing harness.
Either that or Chromium is hanging somewhere.
Here's a few more: BUGWK85771 MAC LINUX : compositing/animation/state-at-end-event-transform-layer.html = TIMEOUT PASS BUGWK85771 MAC LINUX : compositing/geometry/video-opacity-overlay.html = TIMEOUT PASS BUGWK85771 MAC LINUX : compositing/scroll-painted-composited-content.html = TIMEOUT PASS BUGWK85771 MAC LINUX : platform/chromium/virtual/threaded/compositing/visibility/visibility-simple-webgl-layer.html = TIMEOUT PASS
