Issue: Tmux window indicator rendering issue with FiraCode Nerd font in Windows Terminal

Description:

I've been using the catppuccin theme for tmux in combination with the FiraCode Nerd font on Windows Terminal within WSL. However, recently I encountered a rendering issue with the tmux window indicator. Specifically, there seems to be a disconnect between the separator and the window number, resulting in a column of pixels between them.

Steps to Reproduce:

  1. Set up Windows Terminal with WSL.
  2. Use the catppuccin theme for tmux.
  3. Set the font to "FiraCode Nerd".
  4. Open multiple tmux windows.

Expected Behavior:

The tmux window indicator should render correctly with no visual artifacts, and there should be no disconnect between the separator and the window number.

Actual Behavior:

There is a noticeable disconnect between the separator and the window number, resulting in a visual artifact.

Additional Information:

  • This issue appeared suddenly without any changes to my configuration.
  • I've tried troubleshooting by adjusting font sizes, checking for updates, and reviewing configuration settings, but the issue persists.
  • Changing fonts did not resolve the issue, indicating it may not be specific to the FiraCode Nerd font.
  • Screenshots of the issue are attached for reference.

Environment:

  • Operating System: Windows with WSL
  • Terminal Emulator: Windows Terminal
  • tmux Version: Tmux 3.4
  • catppuccin Version: Updated to the last available using tpm
  • Font: FiraCode Nerd

This is a common issue with the way some terminals render fonts.
A detailed explanation can be found here: https://github.com/romkatv/powerlevel10k?tab=readme-ov-file#sub-pixel-imperfections-around-powerline-symbols

What you could try:

  • try a different terminal emulator
  • try a different font
  • increase or decrease the font size

Other than that there is nothing inside of tmux that can be done to address this issue.

or disable sub-pixel anti aliasing fontconfig on linux also fixes the issue if you are fine with that
