Feedback thread ID: 019c2e80-cef5-7882-a6f3-5d064884852c (Feedback recorded, no logs)

Versions:

  • 0.96.0: OK
  • 0.97.0+: BUG
  • 0.98.0: BUG

Environment:

  • WSL2 Ubuntu 24.04.3 on Windows 10.0.26200.7705
  • install: npm -g @openai/codex (also reproduced on Windows npm install)

Steps:
1) Run codex interactive TUI.
2) Ask for a very long novel-length response (streaming).
3) The beginning/top of the assistant output gets truncated/disappears; cannot scroll/copy full message.

Expected: full output remains scrollable/copyable.
Actual: early part is truncated in the TUI during/after streaming.

Thanks for flagging this. To help us reproduce and prioritize:\n\n1. What environment are you using (OS, version, and install method)?\n2. What exact command or config triggers the issue?\n3. Can you share logs or error output if available?\n\nWe will update the proposal once we have the missing details.
