File type icons are half displayed
<!-- bug reporting without issue template will be closed automatically -->

## Expected behavior
Icons need to be displayed correctly as in this screenshot (Image reference: [#1955](https://github.com/SpaceVim/SpaceVim/issues/1955))

## The reproduce ways from Vim starting (Required!)
I'm facing this issue after updating my system (Manjaro). The icons are cropped to half of their size. Please see the below screenshot
