Broken font rendering #4978

Closed lylythechosenone closed 5 months ago

lylythechosenone commented 5 months ago

The problem

There are holes in the rendered font. This only happens with externally-loaded fonts (in this case, Jost from Google Fonts).

Minimal example

import "./Jost-VariableFont_wght.ttf";

export component Main inherits Window {
    Text {
        text: "This is a minimal reproducible example";
        font-family: "Jost";
    }
}
