Summary

Codex Desktop on an Intel Mac has a visual rendering/compositing issue where a dark translucent overlay/shadow appears to cover the area below the composer. Launching Codex with --use-angle=gl fixes the issue while keeping scrolling smooth.

Environment

  • App: Codex Desktop
  • Codex version: 26.519.41501
  • Electron version: 42.1.0
  • macOS: 13.7.8 (22H730)
  • Mac: Intel Mac
  • GPUs:
    • Intel HD Graphics 630
    • Radeon Pro 555

Problem

On the default launch path, the Codex Desktop UI appears to have a dark/transparent overlay or stale compositing layer below the message composer. It looks like something is covering the conversation area.

The issue is visible on the main Codex screen, especially around the lower middle portion below the input composer.

What I tried

  1. Restarting Codex: issue still reproduces.

  2. Disabling macOS automatic graphics switching: issue still reproduces.

  3. Launching with full GPU disabled:

    open -na /Applications/Codex.app --args --disable-gpu --disable-gpu-compositing

What is the expected behavior?
