Terminal keeps scrolling to top of conversation during active session

[Oximito]

Bug Description

During an active Claude Code session in the terminal, the screen frequently and involuntarily scrolls back to the beginning of the conversation. The behavior is erratic/frantic and disrupts the workflow — it's impossible to stay at the current position in the terminal output.

Steps to Reproduce

1. Start a Claude Code session in the terminal
2. Have a conversation with multiple messages (long enough to require scrolling)
3. Observe the terminal jumping back to the top of the conversation automatically

Expected Behavior

The terminal should stay at the current scroll position while the user is working.

Actual Behavior

The screen jumps/scrolls automatically to the beginning of the conversation, repeatedly and without user input. The behavior is frantic and continuous.

Environment

• OS: Windows 11 Home Single Language 10.0.26200
• Shell: bash (Git Bash)
• Claude Code version: (not available — claude --version failed in this environment)

Additional Context

A similar behavior was observed in Google AI Studio a few months ago and was eventually fixed. The symptoms appear to be the same type of terminal scroll hijacking issue.
