Text rendering bug in v2.0.73 - First and last lines of assistant responses missing

Bug Description

In Claude Code v2.0.73 on Windows, assistant text responses have their first paragraph and last line stripped/blanked in the terminal output. Tool outputs render correctly.

Steps to Reproduce

1. Start Claude Code v2.0.73 on Windows
2. Ask Claude to output numbered lines (e.g., "Output lines 1-10")
3. Observe that Line 10 is missing and intro text appears as blank lines

Expected Behavior

All text content should render completely.

Actual Behavior

• First text block before content appears as blank lines
• Last line of each response section is stripped
• Tool outputs (Bash, Read, etc.) render correctly
• Only assistant text responses affected

Environment

• Claude Code: 2.0.73
• OS: Windows 10/11
• Terminal: Both PowerShell and Command Prompt affected

Workaround

Downgrading to earlier version resolves the issue.

Additional Context

• Issue persists with all hooks disabled
• Issue persists without ccproxy (LiteLLM proxy)
• Issue persists in both PowerShell and Command Prompt
• Response content appears correctly in session JSONL logs but not in terminal
