[BUG] Flickering display

Environment

• Platform (select one):
• [x] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: newest
• Operating System: WSL with Ubuntu 22.04 distribution
• Terminal: Wsl1 with Ubuntu

Bug Description

I have switched from WSL2 to WSL1 because of slow file IO on mounted drives in WSL2. Now, when I start Claude code, everything works fine, but the display keeps blinking/flickering when I type and when it’s thinking. It’s like the screen is cleared but not updated fast enough.

Steps to Reproduce

Run Wsl1
Start Claude
Type something

Expected Behavior

A non flickering application like in wsl2

Actual Behavior

Flickering prompt / display

Additional Context

I installed everything in wsl2 and then switched to wsl1 and reinstalled node.
