Describe the bug

When using Claude Code (an interactive CLI tool) with extended conversation history, Warp exhibits aggressive automatic scrolling behavior that makes the tool unusable. Every keystroke causes the terminal to scroll up to the top of the conversation history and then back down to the current position, creating a strobing/flashing effect.

This issue appears to be related to how Warp handles long-running single blocks with thousands of lines of output. Claude Code runs as a continuous interactive session in a single block, and when the conversation reaches a certain length (approximately 5-6 pages of scrollback), the scrolling bug begins.

Key characteristics:

Only occurs after significant conversation history accumulates
Each character typed triggers a scroll to top → scroll to bottom cycle
The entire terminal flashes/strobes, making it impossible to see what you're typing
The issue compounds as more content is added
Cannot use /compact command as I'm leveraging Claude's 1M context window

This appears related to existing issues:

#826 (Console scrolling to top of history)
#1413 (Terminal laggy scrolling with long history)
#4789 (Terminal UI scrolling glitch with long conversation histories)
#10472 (Excessive blank lines causing continuous scrolling)

To reproduce

Open Warp terminal
Start Claude Code: claude
Have an extended conversation with multiple turns (approximately 10-15+ exchanges)
Wait until the conversation history reaches ~5-6 pages of scrollback
Try to type a new prompt in the Claude Code input

Expected result at step 5: Should be able to type normally

Actual result: Each keystroke triggers:

Terminal automatically scrolls to the very top of the conversation
Then scrolls back down to the input position
Creates a rapid flashing/strobing effect
Makes it impossible to see what you're typing
Worsens with each additional character typed

Note: The issue is specific to long-running interactive CLI tools that maintain a single block. The "Maximum rows in a block" setting doesn't help because Claude Code runs as one continuous active block.

Expected behavior

The terminal should maintain a stable scroll position while typing in Claude Code's input, regardless of the conversation history length. The interface should:

Keep the current input position visible and stable
Not auto-scroll to the top of the history when typing
Allow smooth manual scrolling through history when needed
Maintain performance with long-running interactive CLI sessions

Additional context

Environment details:

Using Warp terminal with default configuration
Claude Code version: [corre claude --version]
This issue does NOT occur in iTerm2 or the native macOS Terminal app with the same Claude Code session
The problem is specifically related to how Warp renders and manages scrollback for long-running single-block interactive sessions

Attempted solutions that didn't work:

Adjusting "Maximum rows in a block" setting (doesn't apply to active blocks)
Using different input position settings
Clearing blocks (would lose valuable context)

Partial workaround:

Running Claude Code inside tmux within Warp reduces the issue severity
Suggests this is a Warp-specific rendering/scrollback management issue

Related context:

Claude Code is an interactive AI coding assistant that maintains conversation context
Sessions can easily reach thousands of lines with normal use
The tool is designed for extended interactive sessions
Cannot compromise on context length as it's critical for the tool's effectiveness

Community impact: Multiple similar issues reported (#826, #1413, #4789, #10472) suggest this affects many users of long-running interactive CLI tools, not just Claude Code.

Does this block you from using Warp daily?

Yes, this issue prevents me from using Warp daily.

Is this an issue only in Warp?

Yes, I confirmed that this only happens in Warp, not other terminals.

Hi @AngelGiampierre - couple thoughts:

You're running a version of Warp that's about 5 releases out-of-date; mind updating in case the issue has been resolved since?
The issues you link to seem totally unrelated to what you're reporting here (and one doesn't exist yet at all). Typos?

Is still happening with the last version of Warp and Claude Code

I have a similar issue with scrolling, where the scroll jumps agressively sometimes even jumping and omiting some part of the text, making it unusable.
