And, here is the screenshot of obsidian installed through flatpak,

The first one is using Noto Fonts and the second one is most likely using GNU Free Fonts, which I do not have installed. How can I fix this? Should I open any issue about it in Flatpak or Electron? Currently, I have this nixos configuration,

  fonts = {
    fontDir.enable = true;
    enableDefaultPackages = false;
    fontconfig.defaultFonts = {
      emoji = [ "Noto Color Emoji" ];
      monospace = [
        "JetBrains Mono"
        "JetBrainsMono Nerd Font"
      ];
      sansSerif = [
        "Noto Sans"
        "Noto Color Emoji"
      ];
      serif = [
        "Noto Serif"
        "Noto Color Emoji"
      ];
    };
    packages = with pkgs; [
      adwaita-fonts
      jetbrains-mono
      liberation_ttf
      nerd-fonts.jetbrains-mono
      noto-fonts
      noto-fonts-cjk-sans
      noto-fonts-cjk-serif
      noto-fonts-color-emoji
    ];
  };

Sorry for the inconvenience, I thought I create a new category in my previous post and instantly deleted that, then I realized, I just could have changed the category from “Uncategorized” to “Help”.

does deleting ~/.var/app/md.obsidian.Obsidian/cache/fontconfig/ help in any way?

Does flatpak allow acces to your nix store?

Sadly, It didn’t help.

How can I know that?

Flatseal and similar tools.

I installed it but I don’t know if it allows access to my nix store. Can you check from the screencapture, if it does allow? If not how can I allow that?

Doesn’t look like it was allowed.

Even though you allow read only access to a location that might have symlinks to fints, you simply do not allow the final location of the links to be read.

Inside ~/.local/share/fonts/ there is another directory which includes all the fonts.

[qp@db:~]$ l ~/.local/share/fonts/
lrwxrwxrwx - qp 14 Mar 21:35 system-fonts -> /run/current-system/sw/share/X11/fonts

[qp@db:~]$ l ~/.local/share/fonts/system-fonts
lrwxrwxrwx - root  1 Jan  1970 4x6-ISO8859-1.pcf.gz -> /nix/store/f0nys66h9m6m17l1lb3hwy9a3va1f2ln-X11-fonts/share/X11/fonts/4x6-ISO8859-1.pcf.gz
lrwxrwxrwx - root  1 Jan  1970 4x6-ISO8859-2.pcf.gz -> /nix/store/f0nys66h9m6m17l1lb3hwy9a3va1f2ln-X11-fonts/share/X11/fonts/4x6-ISO8859-2.pcf.gz

I tried add ~/.local/share/fonts/system-fonts:ro manually through flatseal but it didn’t help.

Can you try adding the directory he mentioned?

11

I didn’t understand. Which directory did he mention? /nix/store/?

12

The “nix store”, which is /nix/store indeed.

13

Alright, I did add it but the issue is still not fixed. I also did a system restart afterwards.

This also happens on Brave Browser, I think this is something to do with Chromium and Electron. Because, Firefox based browsers and other applications written Qt or GTK works just fine.

15

Brave is based on Chromium.
