Preflight Checklist

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

What's Wrong?

  • Claude Code version: 2.1.142
  • OS: Linux (KDE Plasma)
  • Terminal emulator: Konsole
  • Shell: bash

The Write tool visualization is broken since 2.1.140 or 2.1.141, the inline code preview only renders some keyword tokens and somehow invisible, as if their foreground color matches the terminal background.

What Should Happen?

This is the expected output I used to have until 2.1.140 or 2.1.141
