[Bug] Scroll input bound to message history prevents viewing previous results

Resolved 💬 16 comments Opened Oct 30, 2025 by temujin9 Closed Apr 7, 2026

Bug Description
I'm unable to scroll back up to look at old results, because somehow you have bound the scroll up and scroll down to your input field. that's super-unhelpful, please revert that change.

This seems contained to a specific session, but persists across separate claude code runs, provided the session is resumed. It does not immediately recur with similar tasks in the same project folder.

The binding of the scroll wheel to up-down on commands persists in the terminal which claude ran in, but goes away with a reset, suggesting it is in some way connected to terminal settings. The reset doesn't prevent a resumption from retriggering the issue.

Same issue here. Let me ask you, have you added a lot of configuration (hooks, commands, etc.) to Claude Code? I just finished a reusable Claude Code configuration to help rebuild context after compaction, and do some other things. Shortly after I deployed it to this project, I began to see the issue, and not once before I deployed it.

temujin9 · 8 months ago

No, I'm using pretty stock Claude with only one MCP (Grafana). I think it was the result of interpreting terminal characters in the output of a command, and then preserving them somehow in the displayed context.

Still seeing this on Claude Code 2.1.3 with GNU Screen 5.0.1.

mariuslacatus · 5 months ago

This happens on macos as well. Quite frustrating to have to use Ctrl+B+[ to be able to scroll up.

Same issue running claude code in tmux session

ryanshepps · 5 months ago

Also running into the same issue in a tmux session

ruben-ondaloop · 5 months ago

Environment:

  • Claude Code: 2.1.34
  • OS: Fedora 43 (Linux 6.17.12-300.fc43.x86_64)
  • tmux: 3.5a
  • TERM: tmux-256color
  • tmux mouse: on (default config)

Behavior:
When running Claude Code inside a tmux session with set -g mouse on, scrolling the mouse wheel cycles through the input
box's message history (previous prompts) instead of scrolling the conversation output vertically. Outside of tmux, mouse
scroll works as expected.

rsdenijs · 5 months ago

Is there a workaround/tmux setting we can use to make this work?

rickycambrian · 5 months ago

Also interested in this since claude code agent teams work much better out of the box than a normal terminal, haven't figured out a good solution to this

tobobo · 4 months ago

I added the following to my ~/.tmux.conf and it fixed it:

set -g mouse on
set -g history-limit 100000

Then, restart your tmux server, or load the config in an active session by pressing ctrl-b, type :source-file ~/.tmux.conf, and hit return
