Note, it may be necessary to disable this test upstream. There is a comment in Chromium's test expectations that this test was failing on several platforms (MacBooks with AMD GPUs in particular, though) and needs to be rewritten. See crbug.com/735483 . Feel free to file a bug on https://github.com/KhronosGroup/WebGL .
