Terminal keeps scrolling to top when conversation gets long

[octoduchilli]

Bug Description

When the conversation feed becomes long enough, the terminal constantly scrolls back to the top automatically. This makes it very difficult to follow the current output and interact with the tool.

Expected Behavior

The terminal should stay scrolled to the bottom (following the latest output), as is standard behavior for CLI tools with streaming output.

Actual Behavior

The terminal repeatedly jumps/scrolls back to the top of the feed, interrupting the user's reading flow. This becomes increasingly frequent and disruptive as the conversation grows longer.

Steps to Reproduce

1. Start a Claude Code session
2. Have a conversation long enough that it exceeds the terminal viewport height significantly
3. Observe the terminal scrolling back to top unexpectedly

Environment

• OS: macOS (Darwin 25.3.0)
• Shell: zsh
• Claude Code: latest version

Impact

This is a significant UX issue — it makes longer sessions nearly unusable as the user has to constantly scroll back down to see the current output.
