Environment

• Claude Code version: 2.1.12
• OS: Linux (WSL2) - 6.6.87.2-microsoft-standard-WSL2

Description

2. Run /resume command
3. Select a past conversation to load
4. Observe screen flashing during load

Expected Behavior

Smooth loading of past conversation without visual artifacts

Screen flashes/flickers while the conversation is being restored
