The test fails with the following at a very low flake rate:
../../third_party/angle/src/tests/gl_tests/VertexAttributeTest.cpp:230: Failure
Expected equality of these values:
angle::MakeGLColor(255, 255, 255, 255)
Which is: White
angle::ReadColor((midPixelX + viewportSize[2]) / 2, midPixelY)
Which is: Transparent Black
