Looks like after the update to webgl/2.0.0/ in https://trac.webkit.org/changeset/264997/webkit We are seeing these new failures webgl/2.0.0/conformance2/rendering/clear-srgb-color-buffer.html webgl/2.0.0/conformance/uniforms/gl-uniform-arrays.html history: https://results.webkit.org/?suite=layout-tests&suite=layout-tests&test=webgl%2F2.0.0%2Fconformance2%2Frendering%2Fclear-srgb-color-buffer.html&test=webgl%2F2.0.0%2Fconformance%2Funiforms%2Fgl-uniform-arrays.html I will add more that I find to this bug
webgl/2.0.0/conformance2/rendering/clear-srgb-color-buffer.html needs an increase to the tolerance. webgl/2.0.0/conformance/uniforms/gl-uniform-arrays.html looks like a flaky timeout in Debug - needs to be marked Slow in Debug.
this one is actually now passing: https://results.webkit.org/?suite=layout-tests&test=webgl%2F2.0.0%2Fconformance2%2Frendering%2Fframebuffer-completeness-unaffected.html
