claude-code [BUG] Claude Code Terminal Refreshes / Sends me to the top of terminal session every 15 seconds

Environment

Platform (select one):
- Claude Max
Claude CLI version: 1.0.6 Claude Code
Operating System: Ubuntu 22.04
Terminal: WSL

Bug Description

The terminal display returns to the top of the claude code terminal history about every 15 seconds, even when I am currently looking / working on things actively at the bottom of the terminal history / session

Steps to Reproduce

Use claude code
Watch it bug out

Expected Behavior

I expected to not be returned to the top of the terminal history every 15 seconds

Actual Behavior

I am returned to the top of the claude code terminal history every 15 seconds

Additional Context

Might have something to do with my switching tabs as I notice it happens less when I stay working with claude code continously

Same here, WSL1 ubuntu 22 and windows terminal, very annoying. Only seems to happen when I'm partially scrolled and looking at diffs. Just started today.

Not WSL, but sometimes when the "refresh spam" happens to me, I can hit "ctrl+r" or even just the up-arrow, and then it stops. I can hit ctrl+r to exit the freeze-frame or hit "down" again as needed at that point.

This is a really severe issue guys, it isn't the same problem as when it would rescroll the history and get slower and slower, it makes it so you can't read diffs. Anyone found a workaround (like running it inside tmux or something)?

Also, Claude code constantly flickers when it is updating progress etc, but that has been an issue longer.

Fix needed! Seeing this on macOS 14.7 + Ghostty.

Resets my scroll position in the buffer, most annoying. Sometimes whole screen flickers (swaps content rapidly) for several seconds before it calms down, usually after long MCP responses (> 1 screen height).

I've been running Claude Code in tmux because of this. The copy mode is essentially a "paused" view of the scrollback buffer, so the issue of jumping while trying to read diffs doesn't happen there. (mentioned here already: https://github.com/anthropics/claude-code/issues/826#issuecomment-2928038872)

Apparently this might be fixed by the recent update? Also mentioned in the other issue.

Apparently, upgrading from 1.0.4 to 1.0.9 restored the former behaviour for me and made it usable again (occasional flicker).

Same here with tmux/kitty - already reported a while back at https://github.com/anthropics/claude-code/issues/947 - this should be super high priority as it directly impacts the usability of the tool especially now that it's no longer in Research Preview beta mode as before!

Massive problem and makes the cpu run hot

I haven't seen this happen lately fwiw. However, the terminal still flickers like crazy in the lower half while claude is working on stuff, so it seems it isn't handling terminal rewrites correctly. A huge block of text flickers even though only the spinner and token count is updating.

The scrollback issue still happens sometimes but not as bad as before

I have this issue too, on macOS/Kitty.
