Comparing the results of the 2.0.0 snapshot: https://www.khronos.org/registry/webgl/conformance-suites/2.0.0/conformance2/textures/misc/tex-srgb-mipmap.html to top-of-tree: https://www.khronos.org/registry/webgl/sdk/tests/conformance2/textures/misc/tex-srgb-mipmap.html the 2.0.0 version fails in Chrome Canary on macOS but the top-of-tree version passes. If I remember correctly, Intel contributed this test and workarounds for driver bugs where mipmaps for sRGB textures weren't generated correctly. I've just filed: Workarounds for sRGB mipmap generation needed on macOS https://bugs.chromium.org/p/angleproject/issues/detail?id=4848 about this. Khronos' 2.0.0 snapshot of this test also needs to be updated, and rolled forward in WebKit too. |
