This bug was filed from the Socorro interface and is report bp-b969897a-451c-4186-9c6d-514de0171017. ============================================================= Seen while looking at beta crash stats: http://bit.ly/2gq2aet. Crashes are all Windows 7. Affects 57/58 only. 308 crashes/251 installs on Beta 8.
The particular crash you linked to there is a dupe of the CompositorThreadHolder::Shutdown() shutdown hang. More broadly, I think the problem here is that mozilla::PrioritizedEventQueue<T>::GetEvent needs to be added to the irrelevant signature list, as was done for a variety of other event queue signatures in bug 1402037. I'll file a bug for that.
Hey Will, do we have any open bugs on adding to those skip frames? Looks like we found another uninteresting middle frame here.

That fix for bug #1409425 went to production earlier today. I reprocessed https://crash-stats.mozilla.com/report/index/b969897a-451c-4186-9c6d-514de0171017?refresh=cache and it's got a different signature now: shutdownhang | mozilla::layers::CompositorThreadHolder::Shutdown Hope that helps!
This signature should be gone now, so I'll close this bug.
