[Bug] Inline-mode scrollback duplication persists on Windows Terminal (2.1.119)
Bug Description
Inline-mode scrollback duplication on 2.1.119 (Windows Terminal + PowerShell). A single assistant response is re-rendered ~10 times into terminal scrollback as text streams. Duplicates are persistent in scroll history, not transient flicker. Reproduces with effortLevel=high on long planning responses, with or without tool calls.
Recent changelog claims this was fixed in 2.1.116 (scrollback duplication, inline mode), 2.1.117 (Ctrl+L / redraw on Windows Terminal), and 2.1.118 (non-fullscreen resize/dialog/long sessions), but it still reproduces on 2.1.119.
Repro:
Windows Terminal, PowerShell profile
/tui confirms inline renderer
effortLevel=high
Send a planning-style query that elicits a long multi-section response
Response renders ~10x in scrollback
Env:
Claude Code 2.1.119
Windows 11
Windows Terminal + PowerShell
inline renderer
CLAUDE_CODE_NO_FLICKER not set
effortLevel high
Settings show autoUpdatesChannel=latest but /config reports auto-update disabled (possible config discrepancy)
Related: #52866 (sequential tool-call re-render), #48318 (general 2.1.x duplication), #11038 (Windows Terminal resize trigger). Possibly same root cause as one of these despite the recent fixes.
Have not yet tested /tui fullscreen for comparison — will follow up in a comment if it changes behavior.

Confirmed duplicate of #57133 — same OS (Windows 11), same shell (PowerShell), same trigger (long multi-section response), same symptom shape. The version difference (I'm on 2.1.119, kriona is on 2.1.133) just confirms the bug spans both versions. Closing in favor of the canonical issue.
