How can I disable anti-aliasing (font smoothing) in Visual Studio Code?

Answer 1

This is what works for me on Ubuntu.

Step 1. Create file ~/.config/fontconfig/fonts.conf, if it doesn't exist.

Step 2. Add this (or update accordingly, if the file already exists):

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<!--ANTIALIAS--><match target="font">
<edit name="antialias" mode="assign"><bool>false</bool></edit>
</match>
</fontconfig>

Note: this will affect all Chromium-based applications (which includes Electron applications).

Answer 2

I couldn't do this though VSCode itself (as it told me workbench.fontAliasing was not a valid setting), however I could apply it system-wide on my Linux machine, by adding this to a file like /etc/fonts/conf.d/99-example.conf:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "urn:fontconfig:fonts.dtd">
<fontconfig>
  <match target="font">
    <test name="family" compare="eq" ignore-blanks="true">
      <string>Monoid</string>
    </test>
    <edit name="antialias" mode="assign">
      <bool>false</bool>
    </edit>
  </match>
</fontconfig>

Change Monoid to the name of the font you do not want to antialias in any program.

Restarting VSCode after creating the file resulted in no antialiasing for that font.
