This issue might be a duplicate of existing issues. Please check:

  • #4027: System theme in macOS with ghostty doesn't apply opacity
  • #4464: Light Mode doesn't work in Zellij

These issues represent a similar pattern of system theme functionality not working correctly in specific terminals. Your Wezterm issue may be part of a larger problem with terminal-specific theme detection.

Feel free to ignore if this is specific to just the 'system' theme option not appearing in Wezterm.
