Actual Behavior
This is without Atlas Engine (MacType enabled)

FYI If you're curious about some of these changes, there's a lengthy discussion over here with the latest update being: #13936 (comment) In short, the blurriness appears to be correct actually/unfortunately.
In the soon to be released next 1.16 update you'll be able to specify precise fractional font sizes which will allow you to restore the previous look of glyphs. Text clarity can be improved if you enable ClearType in your settings. Finally, the reason those rounded corners look worse is because I'm incorrectly handling glyph sizes in AtlasEngine and assume that they're 1 cell wide, even though they're actually 2 cells wide. This is an issue that's specific to Nerd Fonts and is something I'm currently working on as fast as I can.

Good to know, thanks for the fast reply. I'll keep it disabled for the time being and use MacType. Especially the NF symbols (OS logo, folder, git..) look a lot better for the time being.
What I don't understand is why exactly some text gets blurry with Atlas AND MacType

FYI I'm going to continue tracking the issue with nerd font glyphs in #14022, which was the first issue to report it.
