Cannot copy text from Claude responses in interactive TUI (GNOME Terminal, Ubuntu 24.04)

FWIW /tui default fixed this issue for me.

I have the same thing in /tui fullscreen on Fedora 43 - not only does it not auto-copy (though it says it does) but ctrl-shift-C doesn't copy either. /tui default makes it work again.

I'll note that the workarounds given (middle-click) does not work for me

FWIW /tui default fixed this issue for me.

This doesn't fix the issue for me and significantly changes other claude code behavior (e.g., #826), so it's not really a great workaround.

Works for me. The issue only occurred when switching to tui fullscreen a few weeks back.

Works for me.

/tui fullscreen works for you?

This is exactly the issue: cannot copy text from Claude responses in interactive TUI with /tui fullscreen.

No, /tui default works for me.

When I updated Claude a few weeks back, it asked me to try the new fullscreen mode - which I did. This is when I couldn't copy text via mouse. That's the only connection I can make where I started having this issue.

I was able to isolate the mouse selection / copy issue to the fullscreen TUI setting.

The issue occurs when this exists in ~/.claude/settings.json:

{
  "tui": "fullscreen"
}

Environment tested:

SHELL=/bin/bash
TERM=xterm-256color
Connection=SSH
OS=Ubuntu and AlmaLinux

Symptoms:

• Mouse text selection does not work reliably inside Claude Code.
• Copying selected terminal text fails or becomes inconsistent.
• The same SSH client and terminal work normally outside Claude Code.

I tested this on both Ubuntu and AlmaLinux servers. After removing only "tui": "fullscreen" from ~/.claude/settings.json and restarting Claude Code, mouse selection/copy worked normally on both systems.

Workaround:

python3 - <<'PY'
import json, pathlib

p = pathlib.Path.home() / ".claude" / "settings.json"

data = {}
if p.exists():
    try:
        data = json.loads(p.read_text())
    except Exception:
        data = {}

data.pop("tui", None)

p.parent.mkdir(parents=True, exist_ok=True)
p.write_text(json.dumps(data, indent=2) + "\n")
print(p.read_text())
PY

I also confirmed the behavior by restoring the old config with "tui": "fullscreen"; the issue returned immediately. Removing it fixed the issue again.

This appears to be related to fullscreen TUI mode capturing or altering terminal mouse/input behavior in SSH sessions.

Thanks for proving it with the config. Also confirmed same issue

Confirming issue on Mate Desktop (Gnome 2) as well. This fullscreen renderer also prevents logging in, because of the token back and forth process for the claude code client login. Biggest problem is with my VMs that the company wants us to use for sandboxing. It's a Red Hat based solution with Parallels (Gnome 3).
