Win 11 Home 64 bit

What issue are you seeing?

Since a recent update, after processing a task. The mouse gets super laggy and jumps around the screen. System is fine after closing Codex. The bug is not too far from rendering my PC unusable.

What steps can reproduce the bug?

On startup and after working on a task.

What is the expected behavior?

No lag

Additional information

Not sure about this part so take it with a pinch of salt: I think my NVME drive is being hammered IO wise not bandwidth when Codex is idle.

Research direction

Start by reproducing the lag on Windows 11 with Codex version 26.810.41047, both at startup and after a task. Monitor disk I/O and mouse responsiveness while Codex is idle; done means the system stays responsive without sustained unexplained I/O.
