Steps to reproduce the problem:
1. Focus on Omnibox
2. Start typing "testing"

What is the expected behavior?
Expect the Omnibox to show suggestions and have a non-transparent background

What went wrong?
No suggestions and a transparent background (though borders show)

Did this work before? Yes 68.x

Chrome version: 69.0.3497.92  Channel: stable
OS Version: OS X 10.11.6
Flash Version: 

I deleted the `Application Support/Google/Chrome/Default` folder and started from a fresh user. Problem is present even before signing into my Gmail account (which means no extensions associated with my account have been installed or activated yet, I believe).

Also, there seems to be other similar "invisibility" or transparency bugs similar to this: It seems that backface visibility and CSS transforms are impacted (having a transform that changes Z makes the element invisible).
