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?

When the sidebar (chat history) is open and the mouse cursor is moved from the sidebar into the main content area, a narrow empty overlay element appears between the sidebar and the main view. This element is invisible/blank but covers the underlying content of the main view, making it inaccessible.

What Should Happen?

The main content area remains fully accessible and unobstructed.

Error Messages/Logs

Steps to Reproduce

  1. Open Claude Desktop with the sidebar visible
  2. Move the mouse cursor from inside the sidebar into the main content area

Claude Model

Sonnet (default)

Is this a regression?

I don't know

Last Working Version

Claude Code Version

N/A

Platform

Anthropic API

Operating System

macOS

Terminal/Shell

Terminal.app (macOS)

Additional Information

  • Moving the mouse into the main area from outside the app window does not trigger the issue — only the transition from sidebar to main view.
  • Related to issue #50297 (sidebar jitter/ghosting), but distinct: the overlay is persistent and does not resolve without a restart.

extent analysis

TL;DR

The issue can likely be fixed by adjusting the CSS to prevent the overlay element from appearing or by modifying the JavaScript code that handles the mouse movement event.

Guidance

  • Investigate the CSS styles applied to the overlay element to determine why it is being displayed and how to hide it or prevent it from covering the main content area.
  • Review the JavaScript code that handles the mouse movement event from the sidebar to the main content area to see if there are any logic errors or unnecessary element creations.
  • Check if the issue is related to the Sonnet model or if it occurs with other models as well, to determine if the problem is model-specific.
  • Verify if the issue persists when using a different platform or operating system to determine if it's specific to the Anthropic API or macOS.

Example

No code snippet can be provided without more information about the CSS and JavaScript code used in the application.

Notes

The issue may be related to issue #50297, but it's distinct and requires separate investigation. The fact that moving the mouse into the main area from outside the app window does not trigger the issue suggests that the problem is specific to the transition from the sidebar to the main view.

Recommendation

Apply a workaround by adjusting the CSS or JavaScript code to prevent the overlay element from appearing, as the root cause of the issue is likely related to the application's code rather than a versioning problem.
