Looks like there's something racy in the frame comparison. Looking at the log in https://treeherder.mozilla.org/logviewer.html#/jobs?job_id=307819981&repo=autoland&lineNumber=1988 you can see that the tests dump the base64 data URLs for the images if they don't match. It appears that the images are about a frame apart -- will upload them following this comment.

I suspect bug 1544354 will be a similar issue.
