Steps to reproduce the problem:
1. Have a 4K monitor
2. Set windows DPI scaling to 125%
3. Set chrome scaling to 100%
4. Make div within a div and set the innner div background
5. Div background doesn't go all the way to the edge of the outer div, leaving a 1px margin just floating there

What is the expected behavior?
The background should not leave a 1px margin 

What went wrong?
The background leaves weird 1px margins 

Did this work before? Yes 58 I think. Back in September 2016.

Does this work in other browsers? Yes
