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

  • #10951: Similar garbled character display in terminal (triggered by exit command)
  • #7891: Character rendering issues on macOS with iTerm2 (version-dependent)

These issues all share the same symptom of garbled/broken character display on macOS. The fact that resizing your pane fixes the issue suggests it could be a terminal/window size calculation problem in opentui.

Feel free to ignore if none of these address your specific case.
