HiDPI screen has white flickering blocks from time to time.

Reported by lukeshar...@gmail.com, Nov 8 2017 
UserAgent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:56.0) Gecko/20100101 Firefox/56.0

Steps to reproduce the problem:
1. Go to demo.sharefaithwebsites.com/template76/
2. Put in just any email to sign up and get a demo
3. Note that the bottom of the page has blocky squares that flicker from time to time... only in Chrome.

What is the expected behavior?
It should work as usual on other browsers on Ubuntu 16.04 with Linux 4.10.0-38-generic #42~16.04.1-Ubuntu SMP

What went wrong?
Major flickering when the slider is in the right frame.

Did this work before? Yes depends on the computer.

Chrome version: Version 63.0.3239.30 (Official Build) beta (64-bit)  Channel: beta
OS Version: 63
Flash Version: Shockwave Flash 27.0 r0

Specific to Intel+Nvidia HIDPI Dell perhaps?

Checked the issue on reported version 63.0.3239.30  with resolution 1920 * 1080 and DevicePixelRatio=1, unable to reproduce the issue on ubuntu 14.04.

Comment 2 by lukeshar...@gmail.com, Nov 10 2017 

My resolution is twice that, and with a zoom setting of 2 in Ubuntu screen settings so it looks like 1920x1080. On up-to-date system I am not seeing this at the moment, probably a graphics bug.

That was the same type of effect I was seeing. Do you also have an Intel+Nvidia graphics system?

"Unable to reproduce the issue on reported chrome version 63.0.3239.30 and on the latest dev 65.0.3294.0 using Ubuntu 14.04. As ET Hyderabad team doesn't have a HiDPI Linux machine to check for a repro of the issue, hence adding label TE-NeedsTriageFromMTV for further investigation.

Thanks!"
