Confirm this same regression in Tabby (https://github.com/eugeny/tabby), so it is not limited to the VS Code integrated terminal.

Right-clicking to paste in Claude Code inserts the clipboard contents twice. Ctrl+V / Ctrl+Shift+V paste correctly as a single insertion, so the duplication is specific to the right-click paste path, exactly as the original report describes for VS Code.

This broadens the scope: the original is labeled platform:vscode, but the same behavior appears in Tabby while right-click paste still works fine in Windows Terminal (WSL). This points at Claude Code's TUI mouse/bracketed-paste handling under WSL rather than anything specific to the VS Code terminal.

Environment

• Windows 11 Pro, WSL 2 (Ubuntu 24.04.4 LTS, kernel 6.6.87.2-microsoft-standard-WSL2)
• Terminal: Tabby 1.0.234
• Claude Code v2.1.148 (regression introduced in v2.1.143 per the original report; v2.1.142 and earlier were fine)

Repro

1. Copy any text.
2. In Claude Code running inside Tabby, right-click to paste.
3. Text is pasted twice.

Notes

• Ctrl+V / Ctrl+Shift+V paste correctly (once).
• Reproduces in both Tabby and the VS Code integrated terminal under WSL 2.
• Right-click paste works correctly in Windows Terminal (WSL).
• Workaround is keyboard paste, but right-click paste is frequent enough to be disruptive.
