Description

When opening a new tab in the Claude Code desktop app, the tab content area is completely blank — no input box, no UI elements appear.

Steps to Reproduce

  1. Open Claude Code desktop app
  2. Open a new tab (e.g. via the + button or switching sessions)
  3. Click on the new tab

Expected Behavior

The new tab should display the chat interface with an input box at the bottom.

Actual Behavior

The tab content area is entirely black/blank. No input box or UI is visible.

Workaround

  • Resizing the window does not fix it
  • Clicking in the blank area does not fix it
  • The only workaround is to close the blank tab and continue using the original tab

Environment

  • macOS 25.3.0 (Darwin)
  • Claude Code Desktop App
  • Model: claude-sonnet-4-6

extent analysis

TL;DR

The issue may be related to a rendering or layout problem in the Claude Code desktop app, and a potential fix could involve investigating the app's UI rendering logic.

Guidance

  • Investigate the UI rendering logic in the Claude Code desktop app to see if there are any issues with the layout or rendering of the new tab content area.
  • Check if there are any known issues or bugs in the app's version or model (claude-sonnet-4-6) that could be causing this problem.
  • Try to reproduce the issue on a different environment or setup to see if it's specific to the macOS 25.3.0 (Darwin) environment.
  • Consider debugging the app's UI rendering process to see if there are any errors or exceptions being thrown when opening a new tab.

Notes

The issue seems to be specific to the Claude Code desktop app and the provided environment, so any potential fix or workaround may need to be tailored to this specific setup.

Recommendation

Apply workaround: Continue using the original tab and avoid opening new tabs until a fix is found, as this is the only known workaround that allows continued use of the app.
