What happened?
After updating Codex Desktop today, May 1, 2026, the app feels noticeably more sluggish than it did before the update. General UI interactions are less responsive, and the regression was apparent immediately after updating.
Before the update, the same app/workflow felt much more responsive on this machine.
Performance trace
I recorded and uploaded a performance trace as instructed by the app:
43b31e53-6359-468e-89ff-a73a240ecf72
Environment
- Codex Desktop:
26.429.20946 (2312)
- macOS:
26.4.1 (25E253)
- Device: MacBook Pro
Mac15,8
- Chip: Apple M3 Max
- Memory: 64 GB
Expected behavior
Codex Desktop should remain as responsive as it was before the update, especially for normal UI interactions.
Actual behavior
After the latest update, the app feels sluggish during normal use.
Notes
This may be related to other recent Codex Desktop performance reports, but I’m filing this with the uploaded trace ID so the team can inspect the specific capture from this machine.
