Research direction

Start by reproducing the issue on Windows 11 x64 by opening Codex and observing the reported 30-second system and mouse lag. Investigate the startup path and confirm the fix by verifying that opening Codex no longer causes system-wide lag, including after closing the app.

What platform is your computer?

Windows 11 X64

What issue are you seeing?

These two days, as long as I open Codex, my mouse starts to lag. Every time I open Codex, it happens. However, even if I close Codex to the right corner, the lag still exists. Looks like the lag starts with Codex and influences my computer.

I do not use many skills or extensions, and 0 MCP.

What steps can reproduce the bug?

Just open Codex, and always a 30-SECOND LAG.

What is the expected behavior?
