2D quality in Godot 4

[hydroper]

As I understand it, Godot 4 doesn't properly support anti-antialising yet. Is that going to be supported soon?

Another thing: why are fonts pixelated? Are they converted to bitmap? Is there an option to render fonts from their files (e.g. TTF) instead of converting them to bitmap? Any proposal on this? Or is that an issue only when you resize the window, for example? I guess it can be an issue since export platforms can have varying resolution (e.g. a handheld tablet vs a phone).

What do you mean? And where are you getting this?

why are fonts pixelated?

Are they? Are you using bitmap fonts that are pixelated? Otherwise they are rendered via shapes and shouldn't be pixelated

Can you provide examples of them being pixelated

I see, useful! Strange that I enabled MSDF at "Import", re-imported the font and saw no effect. The UI control I was looking at uses a theme that overrides the font for Label and also RichTextLabel. It points to a Roboto regular ttf.

Note that MSDF is not required to get fonts to look smooth. The FreeType rasterizer already antialiases fonts by default, which is what DynamicFont uses.

If your visuals look pixelated, maybe you're downscaling nodes a lot or are using the viewport stretch mode with the window size below the default (or above the default, but with a non-integer scale factor).

The UI component scales its Y from 0 to 1 when it popups and from 1 to 0 when collapsing, so no problem with node scale here. Now, the window resolution, I'm not very sure which is its value, but I suppose it should be an integer?

Which stretch mode are you using? If you're not using the viewport stretch mode, you can use any size you want. However, if using the viewport stretch mode, you need to make sure the window size is an integer multiple of the base size (the aspect ratio can differ if using the keep, keep_width, keep_height or expand stretch aspects). For instance, if your project's base resolution is 640×480, you should only use a window size that is 480 pixels tall, 960 pixels tall, 1440 pixels tall, etc.

See #1666 and https://tanalin.com/en/articles/integer-scaling/ for detailed rationale.

I didn't know what the stretch mode meant, and I wanted aspect = keep, but changing from strech_mode = viewport to stretch_mode = canvas_items solved it. I think that viewport behavior you've described would be complicated as the window resolution can be anything.

Enabling MSDF as mentioned by @AThousandShips at each TTF's Import and changing the window stretch_mode = viewport to stretch_mode = canvas_items, based on @Calinou explanation, allowed the fonts to scale their shape to any size. I didn't test anti-aliasing on bitmaps yet, but I think the quality issue I had was solved.
