+++ This bug was initially created as a clone of Bug #1453797 +++

Originally reported:

Reproducible in Firefox 59-61 for Windows 10.

Steps to reproduce:
1. Navigate to
2. Scroll down to the section "Come on, get appy"
3. Scroll through some of the apps

Expected behavior:
Edges on images are smooth

Actual behavior:
Edges on images are jagged

- Doesn't reproduce in MacOS or Linux 
- Screenshots taken with screenshot tool do not exhibit the issue
- Enabling webrender did not change the result 

layout.css.servo.enabled: true

Without WebRender, we have smooth edges on the first paint (e.g., tab switch), but not once we start using the carousel - probably active layers related.
With WebRender, we never have smooth edges.
This affects Linux + WebRender (at least for me).
