[Bug] Rendering broken after claude --resume on Windows 10 (PowerShell)

Description

After resuming a session with claude --resume <session-id>, the terminal rendering is broken (garbled text, misaligned output). The issue persists until any command is executed (e.g., /status), which forces a re-render and fixes the display.

This occurs with AND without a custom statusline script, confirming it is not a statusline issue.

Steps to Reproduce

1. Start a Claude Code session, do some work, exit
2. Run claude --resume <session-id>
3. Observe broken rendering immediately after resume
4. Run any command (e.g., /status) → display fixes itself

Expected Behavior

Terminal should render correctly immediately after resuming a session.

Actual Behavior

Text is garbled/misaligned after resume. First user interaction (any command) triggers a re-render that fixes the display.

Environment

• Claude Code version: 2.1.37
• OS: Windows 10
• Terminal: Windows Terminal / PowerShell
• Hardware: i9, 128GB RAM, RTX 4090
