this happens for me. using iTerm on mac, claude version 2.1.79.
it only happens when claude is producing output. I scroll up a bit and as soon as it next outputs something, it jumps to the very start of the text. Means you have to wait till its finished before you can read anything

Same, windows 11 wsl, Version: 2.1.76 . Very annoying, adds lots of friction

Still broken as of v2.1.81:

They already did that, it doesn't fix it.

👍 We're experiencing the same issue embedding xterm.js 6.0.0 in a Tauri app. The scroll position jumps when Claude Code redraws its TUI while the user is scrolled up. Confirmed root cause: cursor-up sequences exceeding viewport height + ESC[2J/ESC[3J.

This was fixed in v2.1.101 — Stopped emitting ERASE_SCROLLBACK (CSI 3J) on full resets in non-fullscreen mode, so terminal scrollback is preserved instead of being wiped (which made the view appear to jump to the top of the session) during streaming. If you're still seeing this in the latest version, please comment with your version and repro and we'll reopen.
