This looks like perhaps the test's tolerance should just be increased. Feel free to propose a pull request at https://github.com/KhronosGroup/WebGL .

It seems this test is not a test from the WebGL KhronosGroup test suite. I couldn't find this test in the repository, and neither the test has a KhronosGroup header, like other layout-tests (for instance, LayoutTests/fast/canvas/webgl/webgl-draw-buffers.html).

[Kenneth Russell]

Correct, the fast/canvas/webgl/ tests don't exist in the official conformance repository https://github.com/KhronosGroup/WebGL , but there are similar tests under:

https://github.com/KhronosGroup/WebGL/tree/master/sdk/tests/conformance/textures
https://github.com/KhronosGroup/WebGL/tree/master/sdk/tests/conformance2/textures

and we'd certainly appreciate it if you'd check to see whether these cases are already covered, and if not, adding new tests to cover them. Thanks in advance for your help.
