Go back icon becomes blurry if text scale is greater than 1x

### What Happened?

Scaling the text through Settings/Desktop/Text "blurs" some icons, the most noticeable one is the "go back" icon.
Here's a comparison between the default text scale and 1.25x (which is the one I use due to my big monitor):

### 1.00x

### 1.25x

Take a closer look into the arrow at the left of "All Settings" label.

### Steps to Reproduce

1. Go into system settings
2. Go to Desktop/Text settings and scale it to 1.25x or greater

### Expected Behavior

A good and sharp looking icon, not a blurry one.
