[Bug] Terminal UI flashing/scrolling erratically during manual code review in long chat histories

Bug Description
When the chat history gets long enough and I start manually reviewing/accepting Claude's code changes, the Claude Code window in the terminal starts flashing wildly as it scrolls instantly up to some other area of the chat history then back down to the bottom of the chat. It is very jarring. It is repeatable when creating a sufficiently long chat history then asking Claude to start making some code changes and turning off auto-accept so I have to manually review the changes.
