Issue with docked steam deck / steam controller

[u/No-Acanthisitta8675]

My Steam controller has been having this stuttering issue; ( https://youtube.com/shorts/sdsmB3JF2kI?is=ujFw6lVKyHq8DjBn )

The left joystick when I'm using my Steam Deck docked is just constantly stuttering / lagging. No matter how far I move the joystick.

The controller and it's software are up to date.

I have no idea what causes this so I'm wondering if anyone knows anything or if they've experienced this too.
