I'm not sure why this isn't getting reported on the dashboard.

TL;DR: It's probably all fine. Assigning to Primiano to double check.

All of these are on reported_by_chrome:gpu while on background, and other metrics are still reporting:
https://chromeperf.appspot.com/report?sid=df89f3047ac0f6c7b32f7347328454d5756efab4a7b9be6f8b1584eaa19b3613&start_rev=421711&end_rev=436526

So it's probably an expected side effect of Chrome no longer using gpu memory in those cases.

It's strange, however, that the gpu metric also vanished on some ref builds, e.g.:
https://chromeperf.appspot.com/report?sid=df89f3047ac0f6c7b32f7347328454d5756efab4a7b9be6f8b1584eaa19b3613&start_rev=421711&end_rev=436526

Annie, was there a recent update on ref builds?

+aiolos did update the ref build recently

the benchmark is no more
