1549058 - OSX Mojave (10.14) - image/test/mochitest/test_animSVGImage.html fails on 10.14

Status: NEW

(Core :: Graphics: ImageLib, defect, P3)

Description

[Joel Maher ( :jmaher ) (UTC -8)]

I am working on getting tests to pass in osx 10.14 (vs 10.10 which we currently have).

This causes a few new failures, in this case image/test/mochitest/test_animSVGImage.html fails 50% of the time in both opt and debug:
https://treeherder.mozilla.org/#/jobs?repo=try&revision=34bdc979939c6fb897d4b14cf69b09a2281f84be&searchStr=mochitest-e10s-4&selectedJob=243913231

we have some prior art of failures on osx in bug 1370784, but that is rarely happening.

some related log output:

:aosmond, could you help me figure out how to get this more reliable on osx 10.14 ?

Andrew has a patch for this test in https://phabricator.services.mozilla.com/D12543

It's waiting on some feedback to potentially make the fix a little more complete. You might want to try that patch to see if it helps.

:aosmond - is there any possibility of the aforementioned patch landing in the coming two weeks? As more macosx1010 machines are transferred to macosx1014, there will be increasing need to migrate these suites to macosx1014.
