Bold weight barely distinct

[sharpchen]

I don't have custom font settings, just use the Jetbrains mono out-of-box
The problem is, bold is not bold enough. Only a little thicker I can tell.

EDIT: solved by

config.font_rules = {
  {
    intensity = "Bold",
    italic = false,
    font = wezterm.font("JetBrains Mono", { weight = "Bold" }),
  },
}
