What's Wrong?

The browser pane computer { action: "screenshot" } tool consistently times out after 30s with:

computer timed out after 30s. The Browser pane may be stuck (modal dialog, navigation hang, or unresponsive renderer).

Steps to reproduce

1. Open Claude Code desktop app (Windows 11)
2. Use preview_start with any URL (internal or external)
3. Call computer { action: "screenshot" }
4. Times out every time — restarting Claude Code does not fix it

Environment

• OS: Windows 11 Pro 10.0.26200
• Claude Code: desktop app
• URLs tested: https://google.com

Notes

• navigate works fine (returns 200)
• read_page works fine (returns full DOM)
• Only screenshot / computer actions fail

What Should Happen?

The screenshot should be returned immediately showing the current state of the browser pane, as it does in other sessions/platforms.
