1035473 - WebGL 1.0.3 conformance/textures/texture-attachment-formats.html

Status: RESOLVED FIXED

(Core :: Graphics: CanvasWebGL, defect, P3)

Description

[Walter Litwinczyk [:walter]]

The following WebGL 1.0.3 conformance test fails:

http://www.khronos.org/registry/webgl/sdk/tests/conformance/textures/texture-attachment-formats.html

------------------

After some investigating I'm not sure if the test is correct. For the test cases: LUMINANCE, UNSIGNED_BYTE and LUMINANCE_ALPHA, UNSIGNED_BYTE it assumes that the single value from the texture should be propagated to R, G, and B in a ReadPixels() call.

I tried to find an explanation of what should happen for this case in the WebGL spec and the OpenGL ES 2.0 spec, but came up empty (if someone knows where it is, that'd be helpful!). For comparison I replicated the test using native OpenGL (using an OpenGL ES 2.0 context) on Linux and got the same results as what FF currently does: (64, 0, 0, 255), only copying to the red channel.

@Walter Litwinczyk
Please update the platform to include Windows 7. I tested with the D3D9, D3D11, and native OGL backends on Firefox Nightly38.0a1 (2015-01-30) and it failed on all 3. However it passes on both Chrome 42.0.2291.1 canary and IE 11.

With Intel HD 4000 on Windows 10 and d3d11 backend, I'm getting 1 failure at:

testing: RGB, UNSIGNED_SHORT_5_6_5
FRAMEBUFFER_COMPLETE
PASS should be 0,0,0,255
FAIL at (0, 0) expected: 57,125,189,255 was 189,125,58,255

Passing 65.0 (64-bit) on Windows 10 with Intel HD 4000

I consider this fixed, and any buggy driver for this test should get its own bug.
