I think I know what's going on here. Patch coming up.

Bug 1113425 (specifically, part 2:
https://hg.mozilla.org/mozilla-central/rev/bb3866dea03e) introduced a fix for
a race condition that occurs when querying the animated transform of a layer.
However, that fix failed to update CrossProcessCompositorParent and hence the
issue still arises when e10s is enabled.

This patch applies the fix from that bug to CrossProcessCompositorParent.

Indenting seems wrong here.

Approval Request Comment
[Feature/regressing bug #]: 980770
[User impact if declined]: test_deferred_start.html mochitest fails intermittently
[Describe test coverage new/current, TreeHerder]: seems to be behaving itself on trunk, try run is pretty convincing: https://treeherder.mozilla.org/#/jobs?repo=try&revision=18b5bc538cf8
[Risks and why]: Minimal. This only affects test code when OMTA is enabled.
[String/UUID change made/needed]: None

Two failures on m-i in one day when we didn't have any for a week suggests something landed recently on m-i that regressed this.
The best I can see in that window is:

https://hg.mozilla.org/integration/mozilla-inbound/rev/7e9c4abf391b

We'll get another chance to narrow that down when it hits m-c.
These last two failures are incorrectly filed, but are likely fallout from bug 1159743.
This first fails m-c after the following push:

  https://hg.mozilla.org/mozilla-central/pushloghtml?changeset=34828fed1639

However, nothing in that looks suspicious. The previous merge from m-i to m-c is:

  https://hg.mozilla.org/mozilla-central/pushloghtml?changeset=0f5eacc986e8

which includes some tweaks to OMTA such as:

  https://hg.mozilla.org/mozilla-central/rev/962e15b81684 (bug 947753)

That landed 5 hours before the failure in comment 54 so it could be related, but wouldn't explain the two failures in comment 47 and comment 48.

Changeset 962e15b81684 is going to get backed out in bug 1161049 so we'll see if that makes any difference. If not, then it could possibly be the vsync changes in https://hg.mozilla.org/integration/mozilla-inbound/rev/7e9c4abf391b although that seems unlikely.
