Horrible Controller Aim accelaration

Ever since I downloaded the beta (i play on pc) I have some horrible aim acceleration on the right stick of my xbox one controller (when I touch the end of the ring with the stick). This wasn’t the case before the beta and I have no idea how to remove this. Tried everything in big picture mode. Please help.

Yes I’m having the exact same problem, not enough people mentioning it at the moment.
