Primiano, Juan, any idea what's going on or how I can help debug? It seems like the same metric (background GPU). One build after the stoppage only has a single revision (https://build.chromium.org/p/chromium.perf/builders/Android%20Nexus7v2%20Perf%20%282%29/builds/3605, r440680) but I didn't have time to check if all the next builds contain this rev.

I've split off from this bug data stoppage alerts for:
- some v8 metrics, issue 678912
- some smoothness metrics, issue 678911

All the remaining alerts are indeed about gpu (except for one on cc [1]), and most of them are on background, but a few are on foreground too.

The background cases could be because of a we're genuinely not using any gpu memory any more. I'll try to investigate a bit more.

This alert was found before M-60 branched. Closing as WontFix as this is believed to either be invalid or non-reproducible.
