Flags emoji not rendering correctly on Godot 4.2.1 about godot HOT 6 OPEN

Most likely thorvg related issue (library used to render SVGs). There are 3 common types of color fonts: CBDT/PNG (should always work), SVG (usually works, but depends on thorvg), and COLRv1/CPAL (currently not supported).

Please try in 4.2.2 to make sure this bug hasn't already been solved

Tested now, and it looks the same

from godot.

Interestingly, it works fine with other emoji fonts (such as Twemoji, which I used here)

That is really strange, should not all fonts behave the same? Thank you for recommending a font that works, for now this solves the issue for me.

I'm assuming that the flags on Noto uses some king of SVG path/effect that is not supported by Godot, since parts of the flag that is not wavy does show up, only the wavy part is invisible.

Here's what the Noto svg looks like for the Japanese flag:
