Severe display/rendering corruption in Codex app on Intel Mac

Summary

The Codex desktop app has a severe UI rendering/display bug on my Intel MacBook Pro. Several pages are rendered with large blank or clipped areas, misplaced content, and broken rounded borders/shadows. This makes the app very difficult to use.

I suspect this may be related to the Intel Mac build or rendering path, because the machine is an Intel-based MacBook Pro.

Environment

  • Codex app version: 26.422.71525
  • Bundle identifier: com.openai.codex
  • Mac model: MacBook Pro (MacBookPro16,1)
  • CPU: 2.6 GHz 6-Core Intel Core i7
  • Memory: 32 GB
  • macOS: macOS 14.5 (23F79)
  • Kernel: Darwin 23.5.0
  • Architecture: Intel / x86_64 Mac

Impact

This severely affects daily use of the Codex desktop app. Please help investigate and prioritize a fix, especially for Intel Mac users.

“Electron may have compatibility issues with Intel integrated graphics on Intel-based MacBooks, which can lead to rendering glitches or performance problems.

On macOS, you can force the application to use the discrete GPU to work around this issue. For example:

open -a "Codex" --args --force_high_performance_gpu

Most Chrome/Electron-based applications can be launched this way, which helps avoid rendering errors or lag caused by Intel integrated graphics.”

“Electron 可能与基于 Intel 的 MacBook 上的 Intel 集成显卡存在兼容性问题,这可能会导致渲染故障或性能问题。 在 macOS 上,您可以强制应用程序使用独立显卡来解决此问题。例如: open -a "Codex" --args --force_high_performance_gpu 大多数基于 Chrome/Electron 的应用程序都可以通过这种方式启动,这有助于避免因 Intel 集成显卡引起的渲染错误或延迟。
