Environment

Windows build number: Microsoft Windows [Version 10.0.19042.746]
Windows Terminal version (if applicable): 1.5.10271.0 & 1.6.10272.0

Steps to reproduce

Install any nerdfont
Set up anything that uses powerline glyphs (in my case, bobthefish plugin on fish shell)

Expected behavior

Clean rendering/placement of powerline glyphs (see Color schemes @ https://github.com/oh-my-fish/theme-bobthefish)

Actual behavior

The glyphs have a 1px line of the adjacent glyph color

Funnily enough, you can see the same thing in the powerline setup tutorial: https://docs.microsoft.com/en-us/windows/terminal/tutorials/powerline-setup

Setting "useAcrylic": true and "acrylicOpacity" : 0.899 fixes one glyph, but not the other:

I've tried a variety of rendering options, fonts, sizes, etc, but none completely solve the problem. I also have the Windows text scaling set to 100%. I am on a high-dpi monitor (2560x1440) though.

I searched around and found #3626 #455 #4930 #633 #6669 but those aren't quite what's happening here. Sorry if I missed a dupe.
