Ive been experiencing intermittent system wide mouse stuttering whenever the Codex desktop app is running on Windows 11. This is not a recent issue, I first noticed it around 1.5 - 2 months ago, and it has continued since then.

The stuttering can happen while codex is starting, running in the background, minimized, or sitting idle before I have submitted any prompts. It occurs with both local and Remote SSH projects. The same behavior is present whether my mouse is connected over Bluetooth or by cable, and it stops after codex is fully closed.

To make this report more useful, i asked codex to collect my system specifications, application version, reproduction details, process information, and the troubleshooting steps i have already tried. The full sanitized Codex-generated diagnostic report is available on JotBird here:

Thanks for sharing the detailed report. If the stuttering consistently stops after closing Codex, it does sound like the app is triggering the issue, so hopefully the diagnostics help the team identify the root cause.

does this happen with the ChatGPT Classic App, Web Browser or vscode extension?

What kind of mouse hardware are you using?

I haven’t seen this issue with ChatGPT Classic, the web app, or the VS Code extension. It appears specific to the standalone Codex Desktop app.

My usual setup includes Codex Desktop, ChatGPT Classic, and several VS Code windows open at the same time. The stuttering starts only when Codex Desktop is running and stops after it is fully closed.

I’m using a Logitech G502 X LIGHTSPEED, normally through the LIGHTSPEED USB receiver. I also tested it connected directly by USB cable, and the same stuttering still occurred.

Interesting is the G Hub Software running along side or not? Can you verify this with and without it? Also adjust the poling rate? I mention this because Logitech has become quite aggressive with telemetry and your observations on Codex is something I’ve seen in other applications that are unrelated, that show the similar behavior you are describing.

I already tested this with Logitech G HUB fully closed, including its background processes and the stuttering still occurred. I also tried closing several other background applications and overlays one by one, not just GHUB, but none of them affected the issue. I havent tested different polling rates yet, but Ill try, thanks for the additional suggestion.

I just tested this by lowering the polling rate from 1000 to 125. Rebooted the PC, launched all my usual applications except Codex and the system remained completely smooth. After launching Codex, the mouse started stuttering about ~15 seconds later. It then returned to normal, but the stuttering came back intermittently a few minutes later. So unfortunately, changing the polling rate does not appear to affect the issue. The behavior still seems specifically tied to Codex being running.

I also have a subjective impression that the severity may be related to the number of active Remote SSH connections. With only 1 of my 5 configured servers connected, the stuttering seems less noticeable. With all SSH connections disabled and only local projects open, it also seems closer to the 1-server case. When all 5 SSH connections are active, the stuttering appears more frequent or more noticeable. I have not measured this objectively yet so i cannot confirm it as a fact, but it may be a useful direction for further testing.
