So I use the same screen recorder than you and the same file, but on windows and 32 bits. See the attached video. 

(The bug appears also on Mac OSX on my work computer, but i'm not sure about the bits or version...)

Tested the issue on chrome Stable #55.0.2883.87, Canary 57.0.2963.0 in Windows 10.0 and was able to reproduce the issue.

This is a Non-Regression issue since seeing this from M30 #30.0.1549.0, Making the status to Untriaged so that the issue would get addressed.

Note : Able to reproduce the issue in MAC 10.12.2.

Thank you.

Non-regression CSS issue - someone needs to take a look at this.

This isn't a CSS issue - it's either scroll or paint, I think.

roadirsh@ can you still reproduce this? It sounds like a HiDPi compositing issue.
