Terminal re-renders full banner + prompt repeatedly without window resize

Description

The CC terminal UI repeatedly re-renders the full banner (logo + version + model info) and the current prompt text, creating a cascading wall of duplicate content. This happens without any terminal window resize — the window stays the same size throughout.

Environment

• CC version: v2.1.110
• OS: macOS (Darwin 25.2.0)
• Terminal: iTerm2
• Model: Opus 4.6 (1M context) with medium effort
• Plan: Claude Max

Steps to reproduce

1. Start a long CC session (2+ hours, many tool calls)
2. Use multiple skill invocations (/forge, /proj, /arc, /drive, /vox, etc.)
3. Have stop hooks configured (4 stop hooks in this case)
4. Observe: the banner + prompt re-render repeatedly, each time at a slightly different word-wrap width as if the terminal is shrinking — but it isn't

What happens

The entire conversation display shows the banner block repeated 30+ times, each wrapped at a progressively narrower column width. The prompt text and recent output are duplicated alongside each banner re-render. See screenshot below.

Possibly related

• Stop hooks produce Stop hook error: Failed with non-blocking status code: No stderr output — this may be triggering the re-renders
• The issue started recently (not present in earlier CC versions)
• Only observed in long sessions with many context compactions

Expected behavior

The banner should render once at session start. Prompt text should not duplicate on re-render events.
