Windows Terminal version

1.21.2911.0

Windows build number

10.0.22631.0

Other Software

  1. Oh-my-posh 23.17.0 - 23.20.3
  2. Windows Terminal 1.20.11781.0 - 1.21.2911.0
  3. MesloLGM Nerd Font.
    I've tried it with all sizes of fonts in that font-family.
    Downloaded from same portal, installed in the same way, using settings -> Personalization -> Fonts -> Browse and Install Fonts.
    Clear fonts cache.
    Restart machine on each step.
    Moving all fonts from "good" to "bad" machines

Steps to reproduce

Not sure how to properly describe my issue. And haven't found anything similar.

Three Windows machines, same OS, identical configs for terminal & oh-my-posh theme file.
Two of them have the issue with theme's icons in terminal. They are looking flattish (?) The Windows OS icon looks like a simple square, but on the second machine same icon looks a little bit different due to different angle?

To reproduce:

  1. Run the Windows Terminal with PowerShell session.

Expected Behavior

  1. "Good Machine No 3". Intel based (i7-8750h). That's how it should look like.

Correct rendered version by default, from first session, first run:

Actual Behavior

  1. "Bad Machine No. 1". AMD based (7800x3d). Completely flat, almost fresh system,

    On this machine, the render issue can be temporarily fixed:
  1. just open the terminal's settings tab (can close it or keep it open, doesn't make sense). Doing nothing there.
  2. Re-open or open new PowerShell session
  3. As long as this terminal's instance (process) is working, all new sessions in existing instance and new instances will be rendered correctly.

But as soon as I close that "fixed" instance (i.e. all active Windows terminals) and open a new one, the same render issue appears.

  1. "Bad Machine No. 2". Intel Based (Core Ultra 5 125h). Different angle of icon, fresh system:

For this system, the temporary fix doesn't work at all. Nothing works.
