Fast right direction with mouse movement on xim matrix. Is this the drift issue?

Golo

Hello. I'm using xim matrix with PS5 controller, mouse and keyboard.  So as soon as I got my p5 mate pro I updated it to the beta firmware that is supposed to fix the drift and I completed the controller calibration on a Microsoft edge web page and did exactly what they explain to do to fix the problem. I also switched matrix to ps4 controller setting to make it work, it wouldn't connect with it set as PS5 controller. Unfortunately I still have the problem...  So is this the issue people are having:  When I'm aiming down the sites of a gun and I move the mouse to the left slowly it barely moves the gun to the left slowly but when I slowly move it to the right it moves like 10 times faster to the right instead of going to the right slowly which pretty much makes it impossible to aim and shoot a gun with this issue.

Is this the same problem everyone else is having?  I just feel like it's jittery aiming along with the mouse speed to the right being extremely too fast.  Or has anybody did the beta update and it fixed the issue because it hasn't fixed it for me?
