Display issues on Windows 10: black screen in Windows Terminal, garbled output in CMD

Environment

• Claude Code version: 2.1.20
• OS: Windows 10
• Terminal: Windows Terminal / Windows CMD

Problem Description

Issue 1: Black screen in Windows Terminal

When using Claude Code in Windows Terminal, the screen frequently goes completely black with no output displayed. The application appears to be running but nothing is visible.

Issue 2: Garbled/corrupted display in Windows CMD

When using Claude Code in Windows CMD (cmd.exe), the display becomes garbled/corrupted (screen tearing or character corruption).

Steps to Reproduce

1. Open Windows Terminal or CMD on Windows 10
2. Run Claude Code (version 2.1.20)
3. Use the application normally
4. Black screen (Windows Terminal) or garbled display (CMD) occurs intermittently

Expected Behavior

The terminal should display Claude Code output correctly without black screens or display corruption.

Additional Context

Both issues seem to be related to terminal rendering on Windows 10. The issues occur frequently during normal usage.
