The only modification in that push was to a mochitest that isn't run in that job. I don't see how that could have caused this failure. 

Also, I count 9 other pushes before mine but after your successful retriggers on push https://treeherder.mozilla.org/#/jobs?repo=autoland&revision=223e5900fbbb2140fc274430efd281f5e2a9318a

It is probably one of those. My best guess is this one, which touches some webrender stuff and some reftest stuff:

Yeah, it looks like it was introduced by bug 1466549. I've retriggered the R8 job on the try pushes from that bug to narrow down the source PRs.

Looks like it was introduced by servo/webrender#2797. That's a little surprising to me. The test was already fuzzed for WR, so I'll just expand the fuzzy range to cover the new failure.
