does it goes away with ttf?

btw you need to remove family="Jetbrains Mono" from the config otherwise rio will not load your custom config per style

[fonts]
size = 18
features = []
extras = [{ family = "KoPubWorldDotum_Pro" }, {family= "Noto Color Emoji"}]

[fonts.emoji]
family = "Noto Color Emoji"

[fonts.regular]
family="JetBrainsMono"
weight = 400

[fonts.bold]
family="Jetbrains Mono"
weight = 700

[fonts.italic]
family="Jetbrains Mono"
style = "Italic"
weight = 400

[fonts.bold-italic]
family="Jetbrains Mono"
style = "Italic"
weight = 700

[fonts.ui]
family="Jetbrains Mono"
weight = 700

I tried this configuration but stil not work.
This problem occures when using nerd font v3.3.0 facthed Jetbrains Mono v3.2.0 patched otf fonts works nicely.

[racagogi]

fc-scan JetBrainsMono-Bold.otf | grep weight result
nerd font 3.2.1 weight: 200(f)(s)
nerd font 3.3.0 weight: 146.4(f)(s)
