• Your Windows build number: (Type ver at a Windows Command Prompt)
  Windows 10 18362.30 (Enterprise)
  oh-my-posh 2.0.263 - agnoster theme
  posh-git 0.7.3
  Screenshots taken using Nerd Fonts Inconsolata NF, also tried using FuraCode NF with same results.
  I am using a build from master as of ~11am PDT today.

• What you're doing and what's happening: (Copy & paste specific commands and their output, or include screen shots)
  Windows Terminal
  
  Fluent Terminal (expected result)
  

• What's wrong / what should be happening instead:
  Arrow characters on powerline should be getting rendered a few pixels to the left, so colour gaps aren't visible (see Fluent Terminal screenshot). Screenshots taken using agnoster theme, but the same happens on other themes utilising those arrows - Paradox and Fish. No issues noticed on themes that don't render this arrow character.

Edit: removed ohmyposh disabled screenshot, as that doesn't relate to this issue but to the other one I just opened.
