[Windows 26.818.41509] conversationDetailMode=STEPS_PROSE is overwritten to STEPS_COMMANDS on startup
What version of the Codex App are you using?
Codex Desktop / ChatGPT app for Windows: 26.818.41509
Published: August 22, 2026
What platform is your computer?
Windows
What issue are you seeing?
Codex Desktop does not preserve the Desktop conversation detail setting when I manually set:
[desktop]
conversationDetailMode = "STEPS_PROSE"
After fully closing Codex Desktop, editing the setting, saving the file, and starting Codex Desktop again, the application rewrites it to:
[desktop]
conversationDetailMode = "STEPS_COMMANDS"
This happens automatically on application startup, without me changing the setting in the UI.
Steps to reproduce
- Fully quit Codex Desktop.
- Open the local Codex
config.toml. - Set:
[desktop]
conversationDetailMode = "STEPS_PROSE"
- Save the file.
- Confirm that the file still contains
STEPS_PROSE. - Start Codex Desktop.
- Re-open the config.
- Observe that Codex Desktop has changed the value to:
conversationDetailMode = "STEPS_COMMANDS"
Expected behavior
Codex Desktop should preserve:
conversationDetailMode = "STEPS_PROSE"
If STEPS_PROSE is no longer supported, Codex Desktop should explicitly reject, migrate, or document the setting instead of silently overwriting it.
Actual behavior
Codex Desktop silently rewrites:
conversationDetailMode = "STEPS_PROSE"
to:
conversationDetailMode = "STEPS_COMMANDS"
on startup.
Regression / related issue
This appears to be a regression of issue #23033.
That issue previously reported that conversationDetailMode reverted to STEPS_COMMANDS, and a hotfix was later reported as released.
The same persistence symptom is reproducible again on Windows Desktop 26.818.41509.

Other Windows Desktop issues have also reported config values being overwritten or regenerated on restart:
- #27655 — settings UI / config.toml persistence mismatch
- #25090 — config changes overwritten on restart
Additional information
The setting is intentional. I prefer the prose-oriented conversation detail mode rather than the more command-oriented display.
For privacy reasons, I do not want to upload my full config.toml, because it contains local paths, project names, usernames, and other machine-specific information.
I can provide minimal redacted snippets showing only the affected setting before and after startup, for example:
Before startup:
[desktop]
conversationDetailMode = "STEPS_PROSE"
After startup:
[desktop]
conversationDetailMode = "STEPS_COMMANDS"
I can also provide a screenshot of the About dialog showing version 26.818.41509.
Requested fix
Please make conversationDetailMode = "STEPS_PROSE" persist across Codex Desktop restarts, or clarify if STEPS_PROSE has intentionally been deprecated or replaced.
If the value is still supported, Desktop should not overwrite it with STEPS_COMMANDS during startup.
