This one is pretty bad.

Kats, do you know who owns the vsync code.

Err, that was supposed to be a question of course :)

This happened to me on a QR build today, maybe it's WR-only: https://treeherder.mozilla.org/#/jobs?repo=try&revision=51224f626845eeb752d836dfa0e5845865f2ab05&selectedJob=165975819

I don't think there's any one owner. Most of the people who touched that code are no longer at Mozilla.

This crash might be a different manifestation of the issue in bug 1442730.

Yeah, that CompositorVsyncDispatcher bit mentioned in that bug looks suspicious.

Should be fixed now, see bug 1442730. Closing as WFM since we haven't seen any more of these.
