Double ESC rollback: conversation history not fully visible in Ghostty until window is resized/fullscreened

Bug Description

When using Claude Code in Ghostty terminal on macOS, double-pressing ESC to roll back a conversation turn causes the conversation history to not be fully visible. The content appears truncated/cut off. Resizing or fullscreening the Ghostty window forces a re-render and makes all conversation history visible.

Environment

• Terminal: Ghostty (macOS)
• OS: macOS (Darwin 25.4.0)
• Claude Code mode: flclick / interactive mode

Steps to Reproduce

1. Open Claude Code in Ghostty terminal
2. Have a multi-turn conversation (several exchanges)
3. Double-press ESC to trigger conversation rollback
4. Observe that conversation history is not fully visible — content appears cut off
5. Resize or fullscreen the Ghostty window → conversation history becomes fully visible

Expected Behavior

After double-ESC rollback, the full conversation history should be visible without needing to resize the window.

Actual Behavior

Conversation history is truncated/not fully rendered until a window resize event is triggered (e.g., by fullscreening the window).

Hypothesis

Claude Code's rollback rendering does not trigger a proper terminal viewport refresh / scroll-to-bottom after re-rendering conversation history. The content is rendered but outside the current viewport, and only a terminal resize event (SIGWINCH) causes the display to correct itself.

Workaround

Fullscreen or manually resize the Ghostty window after double-ESC rollback to force terminal re-render.
