The following tests started fail on Mac Chromium probably due to r65449 or r65455. Since I could not understand which revision caused the regression, I'm cc'ing relevant people of both patches. fast/canvas/webgl/draw-arrays-out-of-bounds.html = TEXT fast/canvas/webgl/error-reporting.html = TEXT fast/canvas/webgl/get-active-test.html = TEXT fast/canvas/webgl/gl-bind-attrib-location-test.html = TEXT fast/canvas/webgl/gl-object-get-calls.html = TEXT fast/canvas/webgl/incorrect-context-object-behaviour.html = TEXT fast/canvas/webgl/index-validation-copies-indices.html = TEXT fast/canvas/webgl/index-validation-verifies-too-many-indices.html = TEXT fast/canvas/webgl/index-validation.html = TEXT fast/canvas/webgl/null-uniform-location.html = TEXT fast/canvas/webgl/read-pixels-pack-alignment.html = TEXT fast/canvas/webgl/texImage2DImageDataTest.html = TEXT fast/canvas/webgl/texture-active-bind.html = TEXT fast/canvas/webgl/texture-complete.html = TEXT fast/canvas/webgl/draw-elements-out-of-bounds.html = CRASH fast/canvas/webgl/context-attributes-alpha-depth-stencil-antialias.html = TIMEOUT fast/canvas/webgl/texture-transparent-pixels-initialized.html = TIMEOUT Test results: http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=fast%2Fcanvas%2Fwebgl%2Fdraw-arrays-out-of-bounds.html%2Cfast%2Fcanvas%2Fwebgl%2Ferror-reporting.html%2Cfast%2Fcanvas%2Fwebgl%2Fget-active-test.html%2Cfast%2Fcanvas%2Fwebgl%2Fgl-bind-attrib-location-test.html%2Cfast%2Fcanvas%2Fwebgl%2Fgl-object-get-calls.html%2Cfast%2Fcanvas%2Fwebgl%2Fincorrect-context-object-behaviour.html%2Cfast%2Fcanvas%2Fwebgl%2Findex-validation-copies-indices.html%2Cfast%2Fcanvas%2Fwebgl%2Findex-validation-verifies-too-many-indices.html%2Cfast%2Fcanvas%2Fwebgl%2Findex-validation.html%2Cfast%2Fcanvas%2Fwebgl%2Fnull-uniform-location.html%2Cfast%2Fcanvas%2Fwebgl%2Fread-pixels-pack-alignment.html%2Cfast%2Fcanvas%2Fwebgl%2FtexImage2DImageDataTest.html%2Cfast%2Fcanvas%2Fwebgl%2Ftexture-active-bind.html%2Cfast%2Fcanvas%2Fwebgl%2Ftexture-complete.html%2Cfast%2Fcanvas%2Fwebgl%2Fdraw-elements-out-of-bounds.html%2Cfast%2Fcanvas%2Fwebgl%2Fcontext-attributes-alpha-depth-stencil-antialias.html%2Cfast%2Fcanvas%2Fwebgl%2Ftexture-transparent-pixels-initialized.html&showExpectations=true&useWebKitCanary=true
