Could this be something obscuring the window?

It can't be caused by something obscuring the browser's window; these tests use glReadPixels to read WebGL's back buffer which is definitely unaffected by other windows in the system. Are these flakes seen only on AMD GPUs?

One more occurrence: https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/1676 WebglConformance_conformance_glsl_misc_ternary_operators_in_initializers AssertionError: should be green at (24, 16) expected: 0,255,0,255 was 72,72,72,72 FAIL should be green at (24, 16) expected: 0,255,0,255 was 72,72,72,72

The one in #3 was a webgl_conformance_tests, not WebGL2. Some more failures from last 200 runs, these ones webgl2_conformance_tests: https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/1671 WebglConformance_conformance2_renderbuffers_multisampled_renderbuffer_initialization AssertionError: user buffer has been cleared to green at (8, 32) expected: 0,255,0,255 was 72,72,72,72 FAIL user buffer has been cleared to green at (8, 32) expected: 0,255,0,255 was 72,72,72,72 https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/1584 WebglConformance_conformance_renderbuffers_stencil_renderbuffer_initialization AssertionError: internal buffers have been initialized to 0 at (16, 41) expected: 0,0,0,0 was 72,72,72,72 FAIL internal buffers have been initialized to 0 at (16, 41) expected: 0,0,0,0 was 72,72,72,72

Let's just suppress these flakes on this particular AMD GPU on Windows, referring to this bug. This GPU and driver are flaky and we're working on finding a more recent GPU to upgrade to.

Seeing continued apparently random test failures, though they seem to be clustered in a few individual tests. https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/3919 WebglConformance_conformance2_textures_canvas_tex_2d_rgb9_e5_rgb_float https://chromium-swarm.appspot.com/user/task/422e0c06884bbf10#gpu_tests.webgl_conformance_integration_test.WebGLConformanceIntegrationTest.WebglConformance_conformance2_textures_canvas_tex_2d_rgb9_e5_rgb_float https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/3918 WebglConformance_conformance2_renderbuffers_multisampled_renderbuffer_initialization https://chromium-swarm.appspot.com/user/task/422d8654beb7aa10#gpu_tests.webgl_conformance_integration_test.WebGLConformanceIntegrationTest.WebglConformance_conformance2_renderbuffers_multisampled_renderbuffer_initialization https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/3916 WebglConformance_conformance2_textures_canvas_tex_2d_rgb9_e5_rgb_float https://chromium-swarm.appspot.com/user/task/422ca0454b2c3d10#gpu_tests.webgl_conformance_integration_test.WebGLConformanceIntegrationTest.WebglConformance_conformance2_textures_canvas_tex_2d_rgb9_e5_rgb_float https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/3899 WebglConformance_conformance2_textures_canvas_tex_3d_rg8_rg_unsigned_byte https://chromium-swarm.appspot.com/user/task/4224b0427247cf10#gpu_tests.webgl_conformance_integration_test.WebGLConformanceIntegrationTest.WebglConformance_conformance2_textures_canvas_tex_3d_rg8_rg_unsigned_byte https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/3890 WebglConformance_deqp_functional_gles3_texturefiltering_2d_array_combinations_05 https://chromium-swarm.appspot.com/user/task/4220691009443510#gpu_tests.webgl_conformance_integration_test.WebGLConformanceIntegrationTest.WebglConformance_deqp_functional_gles3_texturefiltering_2d_array_combinations_05 https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/3880 WebglConformance_conformance2_textures_canvas_tex_2d_rgb9_e5_rgb_float https://chromium-swarm.appspot.com/user/task/421c0e7416d87910#gpu_tests.webgl_conformance_integration_test.WebGLConformanceIntegrationTest.WebglConformance_conformance2_textures_canvas_tex_2d_rgb9_e5_rgb_float https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/3862 WebglConformance_conformance2_textures_canvas_tex_2d_rgb9_e5_rgb_float https://chromium-swarm.appspot.com/user/task/42140c83d7e5b910#gpu_tests.webgl_conformance_integration_test.WebGLConformanceIntegrationTest.WebglConformance_conformance2_textures_canvas_tex_2d_rgb9_e5_rgb_float https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/3861 WebglConformance_conformance2_textures_canvas_tex_2d_rgb9_e5_rgb_half_float https://chromium-swarm.appspot.com/user/task/4213897d9af15e10#gpu_tests.webgl_conformance_integration_test.WebGLConformanceIntegrationTest.WebglConformance_conformance2_textures_canvas_tex_2d_rgb9_e5_rgb_half_float https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/3832 WebglConformance_deqp_functional_gles3_texturefiltering_2d_array_combinations_05 https://chromium-swarm.appspot.com/user/task/4206aca67b2fdc10#gpu_tests.webgl_conformance_integration_test.WebGLConformanceIntegrationTest.WebglConformance_deqp_functional_gles3_texturefiltering_2d_array_combinations_05 https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/3830 WebglConformance_conformance2_textures_image_bitmap_from_canvas_tex_2d_rgb9_e5_rgb_half_float https://chromium-swarm.appspot.com/user/task/4205c7d24c632c10#gpu_tests.webgl_conformance_integration_test.WebGLConformanceIntegrationTest.WebglConformance_conformance2_textures_image_bitmap_from_canvas_tex_2d_rgb9_e5_rgb_half_float https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/3829 WebglConformance_conformance2_textures_canvas_tex_2d_rgb9_e5_rgb_half_float https://chromium-swarm.appspot.com/user/task/420553d0f7314e10#gpu_tests.webgl_conformance_integration_test.WebGLConformanceIntegrationTest.WebglConformance_conformance2_textures_canvas_tex_2d_rgb9_e5_rgb_half_float ... Going to attempt to suppress just these individual failures. I doubt that that will address the underlying problem but perhaps it will get the bot back to stability.

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/3a4266303f376d75a334bdb4093bdb2388dbcc15 commit 3a4266303f376d75a334bdb4093bdb2388dbcc15 Author: Kenneth Russell <kbr@chromium.org> Date: Fri Jan 04 01:47:54 2019 Suppress WebGL conformance flakes on Win/AMD. It seems that random tests have become flaky on this configuration, but the failures seem to be clustered in certain tests.

Hopefully that will address all of the flakes on this configuration. We don't plan to revisit these failures on this particular bot so closing this as WontFix. |
