Re-running bisect with wider range; it actually failed to produce values in #11.

Status: WontFix (was: Untriaged)
The numbers have recovered since then: https://chromeperf.appspot.com/report?sid=bd4b5edce438c2cf3745b9ba744de200c6db83d88f3233a1f432fb948af9fec4 (thread_raster_cpu_time_per_frame went down to 1.5ms, and thread_GPU_cpu_time_per_frame went back down to 2.0ms).

And pinpoint is having issues finding a culprit. So WontFix'ing.
