Regression: Weird flickering of the overlay observed on page zoom out.

Reported by lpa...@etouch.net, Aug 16 2016 
Chrome Version: 54.0.2830.0 (Official Build) b6678f521d7dd83c84e701140739cc3b47afe5d8-refs/heads/master@{#412124} (32/64-bit)
OS: Windows (7,8,10)

Steps:
1. Launch chrome and navigate to chrome://tracing
2. Click on 'Record' button and then click Edit categories
3. Now zoom out using Ctrl-- till 25% and observe.

Actual: Weird flickering of the overlay observed on zoom out.

Expected: No such flickering of overlay should be seen.

This is a regression issue broken in M-54, will soon update the other info.

Suspecting: r406156 ?

Please re-assign if your change is not the cause of this issue. 

Note: Issue is not seen in Mac and Linux OS.

It's definitely not 406156 and it's unlikely to be my other change as well. I can look more in a bit, I don't have Windows here right now. Does this not reproduce on Linux?

Also, I can't reproduce this bug... I'll just unassign myself given comment 2.

cc'ing scrolling people though, as it seems potentially overflow: auto related.

Unable to reproduce on any platform. Closing as neither I nor Christian have been able to reproduce it.
