WebGL *textures/webgl_canvas* tests flaky on Windows 7 AMD |
|||
Issue descriptionBoth the WebGL1 and WebGL2 versions of these tests are about 10% flaky on the Win7 FYI Release (AMD) bot. Example flakes: https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/2402 https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/2392 https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/2389 https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/2388 Earliest spotted flake is 13 days ago on August 16 but it is close to the 200 build limit so these tests may have been failing for longer: https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/2250 Failure is always an incorrect pixel color: AssertionError: shouldBe 0,255,0 at (0, 0) expected: 0,255,0 was 72,72,72 FAIL shouldBe 0,255,0 at (0, 0) expected: 0,255,0 was 72,72,72 There are already some similar flaky suppressions, going to broaden them. They were tracked in issue 828984 .
