Sorry about this, that sounds super frustrating!

I've tested Claude Code in Wave and I don't get scrolled to the top (seems to work fine) -- also on MacOS. What shell are you using (bash, zsh)? I'm trying to think of anything that could cause this but coming up pretty blank. Is it happening on every user-input prompt or just sometimes? I just ran through a couple of sessions in a couple different repos and wasn't able to repro the issue.

I'll dig around a bit more and see if there is any xterm.js issues or places where we might inadvertently call a "scroll to top" for that container.

This won't fix your issue, but we did add a new setting term:shiftenternewline that you can set to true which allows you to use Shift+Enter in Claude Code to get newlines instead of having Shift+Enter submit.

Hm, that's interesting. I'm using zsh. I'll try and see if I can dig into what might be unique (broken) about my setup

I'm using zsh and I've encountered the same issue

Additional Feedback from User:

Current Workaround (macOS):

• Control+Down Arrow jumps to bottom of terminal
• Control+Up Arrow jumps to top
  (Note: It's Control, not Command, even on Mac)

Feature Request:
Would be great to have a UI button to jump to bottom (similar to Docker Desktop terminal). Having to use keyboard shortcuts or scroll manually is frustrating, especially when Claude outputs a lot of text and the terminal auto-scrolls to the top.

This would significantly improve the UX for Claude Code users in Wave Terminal.

Hello!
I can tell you I have the same issue on Mac using Claude Code and Wave.

Wave Client Version 0.12.5 (202511250205)

Ctrl + UP / Down doesn't work on my configuration (French Keyboard)
I'm using Option + Up / Down -> Kind of working

Best regards,
JR

When I paste lengthy content into a dialog and press submit, the terminal scrolls to the top, exhibiting the same behavior. In addition, I've noticed that when I hit PageDown and then any key, the terminal will scroll to the top again.

windows环境，远程登陆到linux主机，运行claudecode，面临同样的问题。

I am also having this issues randomly when scrolling as Claude is running.

I am running Pop OS 22.04 with ZSH and Wave 0.13.1

[nateduffy-IG]

This is an issue for me as well!

Same issue here, makes it a killer when you're switching between multiple sessions and trying not to forget what was happening in the other terminal block

Sorry about this, it sounds super frustrating. Been working on some potential fixes #2941 and #2944, but the big problem is I just can't seem to reproduce the issue on my mac or on my windows box. I believe it is happening since there are so many bug reports, but I'm really struggling to figure out what is causing it (been pouring through the Wave and xterm.js code looking for anything that would cause a scroll to top).

If anyone else has this bug please include what platform (macos, windows, linux) you are on. If on mac also please let me know if you have automatic or always for "show scroll bars", and if you are on Sequoia or Tahoe.

Also, are you seeing this when:

• Switching Tabs
• Resizing the Terminal / Window
• When Claude Code asks for input
• When pasting input into Claude Code
• Sometime else?

The more specific with the "when" can maybe help me narrow it down or repro it. Thanks
