As can be seen at http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=fast%2Fhidpi%2Fgradient-with-scaled-ancestor.html, the scrollbars on win/dbg do not match those in win/release (they have a green background). Adding a suppression for now, but this should be fixed (likely by removing the scrollbars from the output).
Win (release) is timing out and Win7 (dbg) has Image failures. Yet our current expectations are: [ Linux Win ] platform/chromium/virtual/gpu/fast/hidpi/gradient-with-scaled-ancestor.html [ ImageOnlyFailure ] [ Win7 Debug ] platform/chromium/virtual/gpu/fast/hidpi/gradient-with-scaled-ancestor.html [ Timeout Pass ] We need Win (release) to also expect Timeout and Dbg to expect Image failures. So I will change this to: [Linux Win] [ ImageOnlyFailure Timeout Pass] In addition platform/chromium/virtual/gpu/fast/hidpi/image-set-as-background.html is timing out on Win (dbg). I will add Timeout to that test as well. I don't know when this started happening. The flakiness dashboard goes back to last week and these failures occurred then. test-results: http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=platform%2Fchromium%2Fvirtual%2Fgpu%2Ffast%2Fhidpi%2Fgradient-with-scaled-ancestor.html%2Cplatform%2Fchromium%2Fvirtual%2Fgpu%2Ffast%2Fhidpi%2Fimage-set-as-background.html
