Preflight Checklist

[x] I have searched existing issues and this hasn't been reported yet
[x] This is a single bug report (please file separate reports for different bugs)
[x] I am using the latest version of Claude Code

What's Wrong?

System Information

OS: macOS 26.5.1
Architecture: Apple Silicon M4 MAX
Claude Desktop Version: Claude 1.12603.1 (3df4fd) 2026-06-11T16:57:36.000Z

What's Wrong?

Claude Desktop becomes unresponsive and renders blank after several days of normal use. The webview freezes on keyboard input; typed characters never appear. The application must be force-quit to recover.

Affects: Both regular Chat and Claude Code

Actual Behavior

Keystrokes freeze the application
Main window becomes blank/unresponsive
Main process event loop stalls for 30-35 seconds
Force quit required to recover
Issue recurs within 1-2 days even after full cache wipe

What Should Happen?

Claude Desktop should remain responsive during normal typing and chat usage over multiple days without degradation or freezing.
