Update: This can be resolved by adding a backface-visibility property of "hidden" to the grandchild elements. Updated demo: https://jsbin.com/boyukihocu/edit?html,css,output

Tested the issue on chrome reported version 64.0.3282.167 using Ubuntu 14.04 with steps mentioned below:
1) Launched chrome reported version and Navigated to URL: https://jsbin.com/boyukihocu/edit?html,css,output(as given in Comment#2)
2) In CSS section, tested the behaviour of the jsbin file by using " /* toggle this on/off to see invisible children: */ "
Observations:
Observed the same behaviour even after making the comment from " /* toggle this on/off to see invisible children: */ " to " toggle this on/off to see invisible children: "

@Reporter:

Thanks for your reply, and for the screencast. My apologies, I should have been clearer on my CSS comment. I intended for the viewer to toggle on/off the "transform: translateX(0)" property below the CSS comment, rather than the comment itself.

Here is a Codepen version, as requested:
https://codepen.io/andyranged/pen/LQQMGr?editors=1100 

Please toggle on/of the "transform: translateX(0);" property at the bottom of the stylesheet to see the behavior I'm experiencing.

OS: Mac OS X

Thank you!

Can reproduce using https://codepen.io/andyranged/pen/LQQMGr?editors=1100  in both stable (64.0.3282.119) and dev (66.0.3346.8) in Linux. 'sub-item' items are not painted in the middle and right-hand column. Firefox renders this example fine.

Ran bisect:

Based on suspect CL, assigning to chrishtr@. Chris, can you confirm if your change caused this regression, and if so whether it's directly from your change or whether your change simply seems to have uncovered a different bug? Thanks.
