Research direction

Start by reproducing both regressions on macOS: switch away from Codex with a floating voice bubble active, then test a spoken response through Bluetooth headphones. Trace the voice bubble rendering and Bluetooth response-audio paths, and consider the work complete when the bubble remains readable and stable while unfocused and responses are audible from the first word.

Description

app bug

Summary

Since the most recent Codex Desktop update, I have observed two voice-mode regressions. This is a user-reported timing correlation; the update has not been confirmed as the cause.

Floating voice bubble rendering becomes unstable

Reproduction

  1. Start a voice session.
  2. Switch to another application while leaving the floating voice bubble active.
  3. Continue the conversation and observe the bubble.

Actual

Text becomes mangled or overlaid, while icons and visual indicators shift position or overlap.

Expected

The bubble should retain a stable layout with readable text and consistently positioned indicators while Codex is unfocused.

Impact

The corrupted bubble is difficult to interpret while working in another application and obscures the voice session’s state.

Bluetooth audio fades in after the response starts

Reproduction

  1. Select Bluetooth headphones as the Mac’s audio output.
  2. Start a voice session and request a spoken response.
  3. Listen to the beginning of the response.

Actual

Audio fades in late. The first sentence begins before it becomes audible and is partially or entirely missed.

Expected

Responses should be audible from the first word.

Impact

Users lose the beginning of responses and must request repetition or consult the transcript, disrupting hands-free use.

Environment

  • Codex Desktop version/build: TBD
  • macOS: 26.5.1
