Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

You mentioned this happened a few weeks ago, did anything change/update on your PC around that time?

Is the controller you use wired or wireless? If wired, have you tried using another USB port?

How often does it occur? Every few minutes or is it less frequent than that?

You never completely lose control of the controller, correct? It will always return to normal after a few moments?

Can you submit a Final Fantasy XIV system report? Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
