[BUG] Paste (Ctrl+Shift+V) broken in GNOME Terminal on Linux/Wayland — regression in 2.1.150

Bug Description

After Claude Code auto-updated to 2.1.150 (May 24, 2026 ~23:03 local), pasting into the CLI prompt no longer works in GNOME Terminal on Ubuntu/Wayland. Ctrl+Shift+V and right-click → Paste both do nothing — no characters appear in the prompt input.

Worked fine for months prior. Repointing the launcher symlink from 2.1.150 back to 2.1.148 and relaunching restores paste.

Environment

• OS: Ubuntu 24.04 (Linux 6.17.0-29-generic), Wayland session (WAYLAND_DISPLAY=wayland-0)
• Terminal: GNOME Terminal 3.52, TERM=xterm-256color
• Claude Code: broken in 2.1.150, working in 2.1.148 (auto-updater install — ~/.local/bin/claude → ~/.local/share/claude/versions/<version>)
• No ibus/fcitx running, no clipboard helpers (wl-clipboard/xclip) installed
• Paste works correctly in every other application in the same session (other terminals, browser, editors, cat, etc.) — issue is isolated to Claude Code

Steps to reproduce

1. Start Claude Code 2.1.150 in GNOME Terminal on Ubuntu/Wayland
2. Copy any text from another app
3. Click into the Claude Code prompt input
4. Press Ctrl+Shift+V

Expected: Clipboard contents appear in the input.
Actual: Nothing — no characters appear, no error, no [Pasted text +N lines] placeholder, no visible response to the keystroke.

Things ruled out

• Restarted xdg-desktop-portal{,-gnome,-gtk} user services — no effect
• Full desktop logout/login — no effect
• Reboot — no effect
• Other apps' paste works fine in same session
• No keyboard-shortcut conflicts (verified in GNOME Settings)

Workaround

ln -sfn ~/.local/share/claude/versions/2.1.148 ~/.local/bin/claude

…then relaunch Claude Code. Also set "autoUpdatesChannel": "stable" and "minimumVersion": "2.1.148" in ~/.claude/settings.json to prevent auto-update reverting the fix.

Possibly related

• #61021 has a comment from @justinclift-prvidr (2026-05-25) reporting the same family of regression in GNOME Terminal on Linux at 2.1.148 and 2.1.150, though that issue is labeled platform:windows / platform:vscode and the OP is about Ctrl+C copy in VS Code, not Ctrl+Shift+V paste in a native terminal. Filing separately because the symptoms and platform are distinct enough that they may have different root causes.
