Workaround:

  • Copying text via keyboard (Ctrl+C after selecting) works fine
  • Mouse-based selection consistently causes the freeze

  • I am using the latest version of Claude Code

What's Wrong?

When attempting to select/copy text using the mouse in the Claude Code Desktop App, the entire screen freezes and turns completely white indefinitely. The same freeze occurs when trying to open the Settings page (e.g. to view remaining credits).

Steps to reproduce (mouse text selection):

  1. Open Claude Code Desktop App
  2. Click and drag with the mouse to select text
  3. The screen immediately turns white and freezes permanently — requires force-closing the app

Steps to reproduce (Settings page):

  1. Open Claude Code Desktop App
  2. Navigate to Settings (e.g. to check remaining credits)
  3. Screen turns white and freezes permanently

Workaround:

  • Copying text via keyboard (Ctrl+C after selecting) works fine
  • Mouse-based selection consistently causes the freeze

Environment:

  • OS: Windows 10 Pro (10.0.19045)
  • Claude Code Desktop App: latest installed version
  • Note: Two versions prior to the currently installed version, these issues did not exist. The app UI appearance also changed significantly after the recent update.

What Should Happen?

Selecting text with the mouse should work normally without freezing the app. The Settings page should open and display correctly without turning the screen white.

extent analysis

TL;DR

The issue can likely be resolved by reverting to a previous version of the Claude Code Desktop App or waiting for a patch, as the problem is identified as a regression introduced in a recent update.

Guidance

  • The fact that the issue is a regression and did not exist in versions two updates prior suggests that the recent update introduced a bug affecting mouse-based text selection and the Settings page.
  • Given that copying text via keyboard works fine, the issue seems specific to mouse interactions, potentially indicating a problem with event handling or rendering in the updated UI.
  • To mitigate the issue, users can use keyboard shortcuts (e.g., Ctrl+C) for copying text until a fix is available.
  • Since the problem occurs on both text selection and navigating to the Settings page, it might be related to a common underlying component or library updated in the recent version.

Example

No specific code example can be provided without more details on the application's internal workings or the exact changes made in the recent update.

Notes

The solution is speculative due to the lack of detailed technical information about the changes made in the recent update. The issue's description suggests a regression, implying that reverting changes or waiting for a patch might resolve the problem.

Recommendation

Apply workaround: Given the information, the best course of action seems to be using the keyboard for text operations and avoiding the Settings page until an official fix is released, as there's no clear indication of when or if a revert to a previous version would be feasible or recommended by the developers.
