Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

No, and I'll explain why below

Describe the bug

If I spawn a new terminal from inside a tmux session: all my commands get a prefix (a command is printed, specifically):

I can see this is coming from: https://github.com/wez/wezterm/blob/main/assets/shell-integration/wezterm.sh#L435

The weird part for me was, that even if I open another terminal (Tilix) I see these WezTerm logs.

But not sure if this is an issue on the WezTerm side or Tmux or Neovim. Any guidance or help would be great.

To Reproduce

1. Open WezTerm
2. create a Tmux session
3. open nvim (nvim --clean)
4. create a terminal buffer (:terminal)
5. run any command

Configuration

local wezterm = require 'wezterm'

return {
  font = wezterm.font("JetBrainsMono Nerd Font"),
  font_size = 12.0,
  color_scheme = "Tokyo Night",
  audible_bell = "Disabled",
}
