AssistiveTouch mouse cursor jumps on iPhone screen

https://youtu.be/aH8SWcvciJk Buggy mouse movement. So i have connected a pc mouse to my iphone using the AssistiveTouch setting. This has worked great but now its like theres a wall in the middle of my phone where the mouse jumps. So i can move it smooth on the left and right side of my phone but when i get to the middle it stops and then jumps like 1 cm. Anyone have any ideas how i can make the mouse movement smooth again as it should be?
