Odd problem with mouse movement recording

Hello Blender people
I have a weird issue where if I record any mouse movement every other frame is zeroed. This means the graphs go up down up down very quickly and the movement is completeley lost. It only happens when I try in the .blend that my current rig set up is in. Start a new blend and it works fine. So, there must be something I’ve changed that is causing this.
Anyone got any ideas on what it could be/ how tofix it?

Thankin’ Y’all
