 Issue 653587  has been merged into this issue.

Also happens for chromium-rel-win7-gpu-intel. See the bug that I marked as duplicate.

It looks like we're getting data again.
https://chromeperf.appspot.com/report?sid=87994713353bc395cc392e9101f1576e36e2d515632630974ab1dc08186a17d9

What happens now?

If you click on the link in #1: https://chromeperf.appspot.com/group_report?bug_id=652731

You'll see that there is no data for the ref builds. The link from #5 is not the ref build. So this is still not getting data.

But if you go to look at https://cs.chromium.org/chromium/src/tools/perf/benchmarks/smoothness.py you'll see ref builds disabled for windows, with a link to  bug 650762  in the comment. So duping against that.
