What version of the Codex App are you using (From “About Codex” dialog)?

What issue are you seeing?

After updating to Codex App 26.422.62136 on macOS, the left navigation/sidebar items have visible UI rendering glitches.

The glitch appears to be connected to cursor activity:

  • When the cursor is idle, the nav items glitch in sync with the normal cursor pulse/blink.
  • When typing, the glitches follow the typing/cursor activity instead.
  • Hovering left nav items causes additional glitches in the nav item background/hover state.

This makes the left navbar visually unstable during normal use.

What steps can reproduce the bug?

  1. Open Codex App 26.422.62136 on macOS.
  2. Keep the left navigation/sidebar visible.
  3. Focus a text input/composer so the cursor is visible.
  4. Stop typing and watch the left nav items while the cursor blinks.
  5. Type in the composer and watch the left nav items.
  6. Hover over items in the left nav/sidebar.

The nav item text/backgrounds visually glitch in sync with cursor blink/typing, and hover states introduce additional background glitches.

What is the expected behavior?

The left navigation/sidebar should render stably. Cursor blinking, typing, and hover states should not cause unrelated nav items or nav item backgrounds to flicker/glitch.

Additional information

I searched for similar existing issues before filing. There are related macOS rendering issues, but I did not find an exact duplicate for left nav item glitches tied to cursor blink/typing/hover state in Codex App 26.422.62136.

extent analysis

TL;DR

The issue can likely be mitigated by reporting the problem to the Codex App developers, as the rendering glitches seem to be a bug specific to version 26.422.62136 on macOS.

Guidance

  • Verify that the issue is not present in previous versions of the Codex App to confirm it's a regression.
  • Try to reproduce the issue on a different platform (if possible) to determine if it's macOS-specific.
  • Provide more details about the system configuration, such as graphics card and macOS version, to help the developers identify the root cause.
  • Check the Codex App's official channels for any known issues or workarounds related to rendering glitches on macOS.

Example

No code snippet is provided as this issue seems to be related to the app's rendering engine rather than a specific code snippet.

Notes

The issue might be related to the specific version of the Codex App and the macOS platform, so it's essential to provide as much information as possible to the developers to help them reproduce and fix the issue.

Recommendation

Apply workaround: Report the issue to the Codex App developers and wait for a fix, as this seems to be a bug that requires a patch from the development team.
