Environment

Windows build number: 19041.388
Windows Terminal version:1.1.2021.0

Actual behavior

Icons in powerline fonts are blurred in the Windows Terminal using 12 pt or lower, therefore ,they are hardly recognizable
The following sample is the Windows logo icon in Windows Terminal, Gnome Terminal on Ubuntu, and ConEmu:

~ 8_13_2020 12_16_06 AM (2)
Windows Terminal, font:3270NF, size:12pt - windows logo not recognizable
C__Windows 8_13_2020 12_29_29 AM
Gnome Terminal, font:UbuntuMono NF, size:12pt - windows logo recognizable
~ 8_13_2020 12_16_12 AM
ConEmu, font:3270NF, size:12pt - windows logo recognizable

I also tested other non-terminal software:
_Untitled - Notepad 8_13_2020 12_39_35 AM
notepad.exe, font:Anonymous pro NF,size:12pt - windows logo recognizable
OneNote for Windows 10 8_13_2020 12_47_00 AM
OneNote for W10 (100% resized), font:3270NF,size=12pt - windows logo recognizable

Thanks for the report! I wonder if there's some sort of hinting instructions we're missing.

If you change the antialiasing mode to cleartype or to grayscale (if you're using cleartype), does it help?

I am using cleartype in above screenshots. Grayscale doesn't help. The powerline icons are still blurry
