I just started seeing frequent renderer hangs while in video Hangouts on my personal speedy device, often just a few seconds after starting the Hangout (it was <5 seconds when I repro'd it twice just now). Hangouts is still working on a 52.0.2743.116 samus and a 53.0.2785.103 peppy device.

I started seeing this yesterday with this version:

Google Chrome	52.0.2743.116 (Official Build) (32-bit)
Revision	9115ecad1cae66fd5fe52bd9120af643384fd6f3-refs/branch-heads/2743@{#728}
Platform	8350.68.0 (Official Build) stable-channel veyron_speedy

It's still happening this morning after an upgrade:

Google Chrome	53.0.2785.103 (Official Build) (32-bit)
Revision	303f356b3441ee792fbd8a53a492eb9280c5e9e6-refs/branch-heads/2785@{#845}
Platform	8530.81.0 (Official Build) stable-channel veyron_speedy

I got a hanging-renderer dialog the first time I saw this this morning. I killed the Hangouts/Gmail process but nothing showed up under chrome://crashes. Here's Chrome's user log from the time of the hang:

The second time, the dialog didn't show up. After 1-2 minutes of Hangouts (and Gmail) being frozen, the Hangouts window briefly switched to fullscreen mode before becoming responsive again and switching to a black screen with white text: "The video call ended because the computer went to sleep." (No, it didn't.)

I see the following in Chrome's user log around the time of the second freeze:

[742:11115:0918/080459:WARNING:audio_input_sync_writer.cc(335)] AISW: No room in socket buffer.
[742:11115:0918/080459:WARNING:audio_input_sync_writer.cc(335)] AISW: No room in socket buffer.

[742:11115:0918/080500:WARNING:audio_input_sync_writer.cc(335)] AISW: No room in socket buffer.

I started a third video Hangout but it hadn't frozen after 10 minutes.

Getting a stack trace when the renderer is killed would be so helpful here. Albert, do you have any ideas about why that isn't happening, or know who might? Also, anyone on the Hangouts side we can loop in?
