I recently filed https://bugzilla.mozilla.org/show_bug.cgi?id=1322266,
which is maybe somewhat similar? Have you tried using mozregression to
single out when this was introduced? If you're clearly able to
reproduce this and you have some idea of when it started, that could
be a quick way to narrow down the root cause. Some information on how
to do that is here: http://mozilla.github.io/mozregression/.
