performance_browser_tests failing on multiple builders

Builders failed on: 
- Win 7 ATI GPU Perf: 
  https://build.chromium.org/p/chromium.perf/builders/Win%207%20ATI%20GPU%20Perf
- Win 7 Intel GPU Perf: 
  https://build.chromium.org/p/chromium.perf/builders/Win%207%20Intel%20GPU%20Perf


It passes about 1 in 10 runs on Win 7 ATI GPU Perf and about half on Intel. Logs look the same:

Unfortunately since it's flaky, I can't figure out a good range to bisect. Assigning to test owner miu, any ideas?
