this bug has been increasing in frequency, almost high enough to look into it.
No longer blocks: stylo-bustage
Whiteboard: [stockwell unknown]
this appears to be stylo specific and we have 20+ in this current week. here is a recent log: https://treeherder.mozilla.org/logviewer.html#?repo=mozilla-central&job_id=125736354 and the reftest analyzer: https://hg.mozilla.org/mozilla-central/raw-file/tip/layout/tools/reftest/reftest-analyzer.xhtml#logurl=https://queue.taskcluster.net/v1/task/Gon_VLVVS3OYGN0VKYdI9g/runs/0/artifacts/public/logs/live_backing.log&only_show_unexpected=1 :xidorn, do you know if there is anything to look at here or a feature to fix in stylo?

This is a stylo-vs-gecko reftest, and the difference is just some subpixel rendering... this is tricky. Given that we don't fail for stylo-vs-stylo, I don't think this is really a big issue. I think the reason that it happens more in the current week simply because we start running tests on linux32-stylo, which may double (or at least increase by 50%) any intermittent frequency on stylo. So I'm not particularly worried about this.
