LayoutTest webgl/1.0.2/conformance/glsl/misc/shader-with-reserved-words.html is a flaky timeout

Comment 1 Ryan Haddad 2017-04-15 15:33:38 PDT
I need to see if there are any code changes that can be blamed. Otherwise, these timeouts may have started after the macOS bots had the latest OS / security updates installed.

Marked test as flaky on mac-wk1 debug in https://trac.webkit.org/changeset/215879/webkit
Comment 3 Ryan Haddad 2017-04-27 10:34:32 PDT
I do not see any obviously related changes before https://trac.webkit.org/changeset/215359/webkit that may explain this.

The test was a flaky timeout before, but the frequency has greatly increased.

The Test has now started to be flaky on debug Wk2 as well. This does not appear to be a recent change. The oldest timeout on the dashboard was on 4/19/2017:
