Texture minification filtering is buggy for LINEAR mode on Mac OSX with Intel GPU |
||||||
Issue descriptionOn Mac OSX with Intel GPUs, if texture magnification filter is set as NEAREST, texture minification filtering is processed as NEARST even minification filter is set as LINEAR. This bug causes failures of texturefiltering tests in WebGL 2.0 dEQP tests. The affected test files are: deqp/functional/gles3/texturefiltering/2d_combinations_01.html deqp/functional/gles3/texturefiltering/cube_combinations_01.html deqp/functional/gles3/texturefiltering/2d_array_combinations_01.html deqp/functional/gles3/texturefiltering/3d_combintations_06.html deqp/functional/gles3/texturefiltering/3d_combintations_07.html deqp/functional/gles3/texturefiltering/3d_combintations_08.html What steps will reproduce the problem? (1) run chrome with --enable-unsafe-es3-apis (2) navigate to https://www.khronos.org/registry/webgl/sdk/tests/deqp/functional/gles3/texturefiltering/2d_combinations_01.html?runSkippedTests=1 What is the expected output? Expect all tests to pass, as they do on other operating systems and on other GPU types on macOS. What do you see instead? filtering.2d_combinations.linear_nearest_clamp_clamp filtering.2d_combinations.linear_nearest_clamp_repeat filtering.2d_combinations.linear_nearest_clamp_mirror filtering.2d_combinations.linear_nearest_repeat_clamp filtering.2d_combinations.linear_nearest_repeat_repeat filtering.2d_combinations.linear_nearest_repeat_mirror filtering.2d_combinations.linear_nearest_mirror_clamp filtering.2d_combinations.linear_nearest_mirror_repeat filtering.2d_combinations.linear_nearest_mirror_mirror
