Alot of screen flickering

Summary

TUI auto-scrolls to bottom and flickers while reviewing pending edits,
preventing scroll-up review

Expected Behavior

When scrolling the TUI while accepting or rejecting changes, I expect to be
able to scroll up freely and read what the model edited/did. The view should
stay wherever I scroll until I choose to move, so I can review any part of the
screen and confirm changes at my own pace.

Actual Behavior

Instead of letting me review the edits, the screen flickers and snaps me back
to the very bottom, where I can only see the latest edits. Even at the bottom
of the screen the flickering continues — the TUI appears to keep
refreshing/re-rendering.

Steps to reproduce the issue

Steps to Reproduce

1. Start a session where the model makes edits requiring accept/reject.
2. While changes are pending, scroll up to read earlier edits.
3. Observe the view jump back to the bottom.

Impact

• Cannot scroll up to review edits before accepting/rejecting.
• Screen flickers constantly (continuous re-render), even when scrolled to the
  bottom.
• Forced to bottom of output, only latest edits visible.

未指定源文件、测试或入口点。在使用 zsh 和 iTerm2 的 macOS 上审查待处理编辑时，在 TUI 中重现该问题，然后跟踪滚动和刷新的行为。当视图在 accept/reject 审查期间保持在所选滚动位置且不持续闪烁时，即表示完成。
