What's Wrong?
Description
Claude Code's terminal output is rendering with severe visual layout glitches, causing large horizontal gaps, missing characters, and broken sentences mid-line. Text formatting and word spacing are completely broken, making logs and explanations unreadable.
Steps to Reproduce
- Execute a command that returns long, multi-line paragraph text or code audit results (e.g., analyzing service files/gating logic).
- Observe the text layout rendering in the terminal.
Expected Behavior
Text should render sequentially with normal word spacing, wrapping cleanly across lines without arbitrary gaps or missing string segments.
Actual Behavior
The terminal output contains large white-space gaps within sentences (e.g., "locally flip SHOW FEE", "server query )", "confirmed ero"). Whole blocks of text appear shifted or partially erased.
