I see 4 failures, 3 on http://www.youtube.com and 1 on Wikipedia. I'm going to start with a bisect on youtube on a wide range and see if Pinpoint detects anything.

Hey Chris, looks like bisect found your CL to be the cause of some flaky failures of the smoothness.top_25_smooth benchmark on some of the Mac perf bots. Here's the log from one of the failing test runs. I think it's a tab crash? https://chromium-swarm.appspot.com/task?id=3ba6a19eb900cc10

This was reverted cause of other crashes -- hopefully will not re-occur when i re-enable (if so, please re-file). |
