The title of the Valve SIGGRAPH 2007 paper on signed distance fields (SDF) is important to pay attention to: "Improved Alpha-Tested Magnification of Vector Textures"...

"Improved" -- not perfect. It's an approximation and fails in many cases. "Alpha-tested" -- not multicolor, monochrome only. "Magnification" -- not minification. No point in using SDFs if you aren't going to magnify shapes.

I see a lot of use of SDF when it's either insufficient (e.g. detailed small text) or overkill (e.g. text rendered at a fixed size). Remember: SDF is not "how you render text on GPU". It's just improved alpha-tested magnification.

Its definitely not perfect, but MSDF goes a long way into fixing the corner-sharpness. I do have some low-DPI small text rendering issues. Will pathfinder fix that?

Yes, that's what Pathfinder is designed to do. BTW, msdfgen fails on a lot of fonts. I can give examples where it just blows up.

I know its terrible, is that actually unfixable btw? Or just needs more R&D

It’s inherent to the approach. It’s one of the reasons why Pathfinder doesn’t use SDF or mSDF

Ahwell, happy you are building/researching Pathfinder. But for my limited usecase msdf will do for now.
