Summary

Scrolling in the Claude Code TUI is far too fast in Cursor's integrated terminal on macOS. It remains too fast even with CLAUDE_CODE_SCROLL_SPEED=1 (the documented minimum) and on a version well past the v2.1.153 trackpad fix.

Environment

  • Claude Code 2.1.162
  • Cursor 3.1.0-pre.11.patch.0 (TERM_PROGRAM=vscode)
  • macOS 15.7.5 (24G624)
  • Shell: fish (/opt/homebrew/bin/fish)
  • "tui": "fullscreen", CLAUDE_CODE_SCROLL_SPEED=1

Steps to reproduce

  1. Run Claude Code in Cursor's integrated terminal with "tui": "fullscreen".
  2. Set CLAUDE_CODE_SCROLL_SPEED=1.
  3. Scroll the transcript with a trackpad/mouse wheel.

Expected

A small, controllable number of lines per scroll notch.

Actual

The view jumps many lines per gesture; CLAUDE_CODE_SCROLL_SPEED=1 provides no further relief since it's already the floor. terminal.integrated.mouseWheelScrollSensitivity has no effect on the captured TUI.

Notes

  • This appears to be the same problem as the now-locked #45537, which was auto-closed as a duplicate of #42297 — but #42297 ("No-flicker mode causes mouse scroll input to be interpreted as text") is a different bug, and multiple commenters on #45537 disputed the merge. The bot on #45537 instructs filing a new issue and referencing it.
  • Possibly related but distinct: #56546 (fullscreen TUI janky/chunky scrolling).
  • Workaround that helps: /tui default (also reported by a commenter on #45537). Requesting a fix (or a sub-1 multiplier / Cursor-specific scroll handling) so fullscreen mode is usable.

This is not a duplicate of #56546. They're distinct symptoms:

  • #56546 — scrolling is janky / chunky / non-smooth (the view jumps in large steps instead of gliding). That's a smoothness/stepping problem.
  • This issue (#65323) — scrolling is too fast: too many lines advance per scroll notch in Cursor on macOS, and it stays too fast even at CLAUDE_CODE_SCROLL_SPEED=1 (the documented minimum). That's a sensitivity / mouse-event-forwarding problem, not a smoothness one.

This is the same problem as the now-locked #45537 (which was itself wrongly auto-closed as a duplicate of the unrelated #42297). Per the bot's own guidance on that locked issue, filing fresh and referencing it. Please keep open.

Also experiencing this on the Windows 11 version of fullscreen TUI mode for Claude Code in the terminal (which seemed to launch or at least show up for me in the past couple days)

its kinda fixed since some version from 1-2 weeks ago, it introduced wheelScrollAccelerationEnabled flag in settings, and i set scrollspeed to 1, now tui fullscreen feels smooth
