Able to reproduce the issue on Windows 7 using chrome latest canary-61.0.3160.0.
Manual bisect info:

Bad build : 61.0.3155.0-Revision-485784

Per revision bisect info:
------------------------
You are probably looking for a change made after 485667 (known good), but no later than 485668 (first known bad).
CHANGELOG URL:
The script might not always return single CL as suspectas some perf builds might get missing due to failure.

I was unable to reproduce this on Chrome 61.0.3159.6 on Windows 10 or Chrome 61.0.3160.0 on Windows 7. The suspected CL is unrelated to scrolling or the UI code.

Leaving this untriaged for the scrolling team to take a look at.

I can't reproduce on 61.0.3162.0. This looks more like a graphics issue than scrolling. Can you try again on the latest Canary?

With response to comment #4,
Retested on latest chrome canary #61.0.3163.0 on Windows(7,10) OS and issue is not reproducible (i.e all contents load properly when autoscrolling).

Thank you..
