Issue 762465: Regression in scroll event frequency

Reported by, Sep 6 2017 Project Member

Issue description

Scroll event frequency seems to have massively regressed in the latest Canary (spotted on both OSX and Android). - compare stable to Canary. Observe how frequently scrollTop/Left update.

I wonder if is related.

Version 63.0.3205.0 (Official Build) canary (64-bit).

I'm increasingly convinced is related. Painting seems to be throttled to the same degree.

This would be very bad (so RBB), but yeah  issue 762043  sounds like different symptoms of the same issue.

You are probably looking for a change made after 498620 (known good), but no later than 498640 (first known bad).
