Summary

Single responses are being repainted multiple times in the VS Code integrated terminal. Same response stacked back-to-back, each with its own bypass-permissions input prompt below it. Non-deterministic — sometimes 0, sometimes 2-3, sometimes 7+ copies in a row.

Environment

• Claude Code: 2.1.119
• Terminal: VS Code integrated terminal
• OS: macOS Darwin 24.5.0
• Model: Opus 4.7 (claude-opus-4-7[1m])

Symptom

• Started after upgrading from Opus 4.6 to Opus 4.7
• Tends to hit longer formatted responses (markdown tables, multi-section output) but not exclusively
• Underlying response is single-copy — confirmed it is a render-side duplication, not generation
• Each duplicated render includes its own input prompt box, so the whole UI element repeats, not just the text
• Does not occur in any other terminal tool, only Claude Code

Notes

• Already on 2.1.119 which includes the April 20-23 VS Code render fixes (v2.1.116, v2.1.110). Those did not resolve this.
• Possibly related to issue #50689 (Opus 4.7 duplicated lines), though that issue is about file content vs. terminal rendering.

Screenshots attached.
