The following WebGL / compositor tests are failing when run in DRT/NRWT (--platform chromium-gpu) and need to be investigated. compositing/webgl/webgl-background-color.html compositing/webgl/webgl-reflection.html
compositing/webgl/webgl-reflection.html passes now that reflections are implemented (though it may still need baselines for Mac and Linux). compositing/webgl/webgl-background-color.html fails because the two purple squares are not of identical color: http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=compositing%2Fwebgl%2Fwebgl-background-color.html&showExpectations=true&group=%40ToT%20GPU%20-%20chromium.org
LayoutTest failures for Chromium are being marked WontFix. The Bug is still accessible and referenced from TestExpectations.
