Unable to enable ligatures on VSCode

[josecastillolema]

Hi, for some reason I am unable to enable ligatures on VSCode using JetBrains Mono.

VSCode setup:

{
    "editor.fontFamily": "JetBrains Mono",
    "editor.fontLigatures": true,
}

The font gets properly loaded but the ligatures won't work. If I replace the font with another one with ligature support, i.e.: Fira Code, ligatures work normally.

Have tried in two environments with the same results:

• Environment 1:
  • Fedora Sericea 39
  • VSCode 1.84.1 installed via FlatPak
  • jetbrains-mono-fonts-2.304-3.fc39.noarch installed via rpm-ostree

• Environment 2:
  • Fedora 39 toolbox
  • VSCode 1.84.2 installed via rpm (https://packages.microsoft.com/keys/microsoft.asc)
  • jetbrains-mono-fonts v2.304 installed via manual installation

Notes:

• The font works normally with ligatures on other programs, i.e.: Gnome TextEdit, Emacs, etc.

I'm not sure if flatpak can touch the fonts :thinking: I definitely recall giving up on some browser in snap, because of the same issue.

Can't reproduce, cause I have the fonts installed in $HOME/.local/share/fonts/ (← this should be a workaround)

Hi @mfocko , thanks for taking a look! Your answer pointed me in the right direction, for some reason I had the fonts installed here: $HOME/.local/share/fonts/ which somehow was producing the error. After deleting this folder and only leave the rpm installed ones ligatures are working. Thanks
