Font with small size doesn't look pixelated in newest version

Godot Version

4.6.1

Question

Hello.

I just switched my project from Godot 4.2 to Godot 4.6.1 and now my font looks high definition, in the editor and when I run the project, despite the fact that the content in the game is inside a low resolution Subviewport.

I am working on a pixel art project and I want my font to be pixelated like that. Is important to note that my font is not a pixelated one, is simply a normal font with a small size inside the Godot project.

I wonder if there is any option inside project settings to change this, I have already searched and found nothing.

Here are some screenshots from the editor difference.

Thank you!
