Additional Information

Here's what I tried before submitting the bug report. Nothing below worked

  1. Switch the extension to terminal mode
  2. Check your context usage
  3. Clear the IDE lock
  4. Disable GPU acceleration on Linux
  5. Disable extension autosave

extent analysis

TL;DR

The issue can be potentially resolved by investigating the compatibility of Claude Code version 2.1.123 with the VS Code integrated terminal.

Guidance

  • Verify if the issue persists when using a different terminal or shell outside of VS Code to isolate the problem.
  • Check the VS Code settings and extensions for any potential conflicts with Claude Code.
  • Consider testing an earlier version of Claude Code, such as 2.1.116, to see if the issue is a regression.
  • Review the /doctor output for any clues about the environment or configuration that might be contributing to the problem.

Example

No specific code snippet is applicable in this case, as the issue appears to be related to the interaction between Claude Code and the VS Code environment.

Notes

The fact that typing works fine in the terminal outside of VS Code and with other agents suggests that the issue might be specific to the integration of Claude Code with the VS Code terminal.

Recommendation

Apply workaround: Try using a different terminal or shell outside of VS Code to see if the issue persists, and consider testing an earlier version of Claude Code to isolate the problem.
