Able to reproduce the issue on reported chrome version 70.0.3522.0 also on latest chrome 70.0.3527.0 using Mac 10.13.1 hi-dpi and Windows 10 hi-dpi.  

Note: Issue not observed on Linux as much as Mac and Windows, If required feel free to add Linux label to it.

Same behavior is seen on M60(60.0.3112.113) hence considering it as non-regression and marking it as Untriaged.

Thanks!

I can't reproduce this on Mac HighDPI. I think this is just antialiasing in action.

Leaving it open in case someone else can reproduce and look into the exact calls we are making to render the gradient.
