[walt93]

Environment

• Platform (select one):
  • Anthropic API
  • AWS Bedrock
  • Google Vertex AI
  • Other:
• Claude CLI version: 1.0.6 (Claude Code)
• Operating System: macOS 15.3,
• Terminal: IntelJIdea Build #IU-231.8770.65

Bug Description

Context was probably >50% full, I issued a command to Claude code and the terminal started scrolling at high speed. Grabbing the thumb, and moving it about did not stop the scrolling, nor did any keyboard keys ESC RETURN CTRL-C repeatedly hit.. The spinner indicating a terminal tool was running never stopped, and after more than 2 minutes I shut down the IDE. Obviously it cannot scroll infinitely, but it was moving at GPU accelerated speeds and I could not make heads nor tails of what it was doing.

Steps to Reproduce

1. Use Claude code until
2. ???

Expected Behavior

Not that.

Actual Behavior

Not seen before.

Additional Context

I got nothing.

yup noticing the same thing . Sometimes it get's stuck when scrolling, especially upwards.

Running Claude 4 in Claude Code through WSL in Windows 11. Worked great all day, but then started endlessly yoyo scrolling for the past 30 minutes. Only thing that would stop is was closing the window, so not an IDE problem, but a Claude Code issue.

Same problem. I was hoping to find some setting to clear buffer or stop the scrolling.

same problem, claude code scrolling super fast strangely

[DeJarnett]

I'd be glad to even just figure out what triggers this (if anything) so I could avoid it.

I've faced this as well. At least on mac, if I press esc a couple of times, it will get out of this madness 😄 And then i just tell it to "carry on" and it will usually resume

Same problem only thing I can do is esc and say continue, sometimes I have to control-c or control-z to break it and reopen. This is on Ubuntu LTS
