Flaky failures of WebglConformance_conformance_glsl_variables_gl_frontfacing in webgl_conformance_d3d9_passthrough_tests |
||
Issue descriptionA couple of failures of this test have been seen here: https://ci.chromium.org/buildbot/tryserver.chromium.win/win_optional_gpu_tests_rel/22646 https://chromium-swarm.appspot.com/task?id=3c66d2fd01ddc610&refresh=10&show_raw=1 https://ci.chromium.org/buildbot/tryserver.chromium.win/win_optional_gpu_tests_rel/22669 https://chromium-swarm.appspot.com/task?id=3c67e88300ea4410&refresh=10&show_raw=1 Also the failure seen in Issue 825413. The failure logs are different; in the first one above, some color channels are non-zero, for example: at (6, 30) expected: 0,255,0 was 255,0,0 FAIL should be 0,255,0 at (6, 30) expected: 0,255,0 was 255,0,0 should be 255,0,0 where in the second one, it looks like the context might have been lost because all of the read-back values are zero: at (6, 30) expected: 0,255,0 was 0,0,0 FAIL should be 0,255,0 at (6, 30) expected: 0,255,0 was 0,0,0 should be 255,0,0 ANGLE's D3D9 backend is not the top priority so I will mark this test flaky and close this as WontFix.
