Linux kernel version: 4.15.0-34-generic

Example of resource heavy website: ads.google.com

Also, not sure if this will make a difference, but 1 or 2 versions ago, when there was no flickering, I had "Use system title bar and borders" enabled.

I'm going to enable it again and see if that solves the problem. I will report back soon.

Yep, that has solved the problem.

I can therefore confirm that the UI flickering only happens when the "Use system title bar and borders" option is disabled.

Unable to reproduce the issue on chrome reported version# 69.0.3497.100 using Linux 14.04 with steps mentioned below:
1) Launched chrome reported version and opened the URL: ads.google.com
2) Enabled "hardware acceleration" from Chrome://Settings and "Use system title bar and borders"
3) Used chrome for a while and didn't observed any flickering in the UI
Observations: Also tested the behavior by disabling the "hardware acceleration" from Chrome://Settings and didn't observed flickering in the UI
