Issue description

Hi, My game asset is design for 640x480, But I don't want set viewport to 640x480. I want use 1920x1080 as viewport size and use camera2d zoom to fit

This is my project setting:

Camera2d is child node of player node, and set camera2d zoom to 3
the text in richtextlabel in player will look like:

But if set ProjectSetting Display/Window/Stretch/Scale to 3, and set camera2d zoom to 1:

It seems normal

Steps to reproduce

Pls look uploaded project

This is expected, as font oversampling does not take camera zoom into account by design. (It would be too slow otherwise.)

To have a font that renders crisply at any resolution without requiring oversampling, use a MSDF font. If not using a custom font, this can be done by enabling Default Font Multichannel Signed Distance Field in the advanced Project Settings. If using a custom font, this can be done by checking the Multichannel Signed Distance Field property in the Import dock after selecting a font file in the FileSystem dock, then clickin Reimport.
