What issue are you seeing?

When using Codex CLI on macOS, the terminal output behaves normally — scrollback works, and the UI rendering is stable.

However, on Windows (especially when using Windows Terminal with WSL or PowerShell), I frequently encounter rendering issues:

• Scrollback does not work correctly (older output disappears or cannot be accessed)
• Output is sometimes overwritten or re-rendered incorrectly
• Text may appear duplicated or partially missing
• Scrolling during streaming output can cause content to be cut or misaligned

This issue appears consistently on Windows Terminal, but does not reproduce on macOS terminal environments (e.g., iTerm2 / default Terminal with similar configurations).

This suggests a platform-specific compatibility issue between Codex CLI TUI rendering and Windows terminal emulators.

What steps can reproduce the bug?

1. Open Windows Terminal (PowerShell or WSL)
2. Run codex
3. Send a prompt that produces long output (longer than one screen)
4. While output is streaming:
   • Try scrolling up
   • Or wait until output finishes and then scroll
5. Observe:
   • Earlier content is missing or cannot be scrolled back to
   • Output may be overwritten, duplicated, or visually corrupted
     Control experiment:
6. Repeat the same steps on macOS (Terminal or iTerm2)
7. Observe that:
   • Scrollback works normally
   • Output rendering is stable and consistent
