Images blurry in Background selection screen when scaling > 100%

[Pierre Equoy]

Image: 19.10 beta – http://cdimage.ubuntu.com/daily-live/20190926.1/eoan-desktop-amd64.iso
Device: Dell XPS 13 7390 (201908-27305)

Steps to reproduce:

0. Go to Settings > Devices > Displays and make sure the scaling is 200% or more
1. Go to Settings > Background

Expected result:

1. The thumbnails for the suggested backgrounds are sharp

Actual result:

1. The thumbnails are blurry.

I attached 3 screenshots of the Background screen at different scales (100%, 200%, 300%).

This is a problem for people with UHD (4K) screens which are likely to select a 200% scaling.
