Slow Joystick on Switch Pro Controller

[Bavario]

Dear Dolphin-Forum,

I've got a problem with my Switch Pro Controller. When I try to move with the joystick, Mario moves incredibly slow. When using the D-Pad however, everything works as expected. Here you can see a clip (sorry for lag):

Is there a setting to fix this maybe? Or is it just the Pro Controller's fault?

thanks in advance

Please acquire a recent version of Dolphin. Dolphin 5.0 is over 4 years old.

Recent versions replace the confusing to configure "Radius" setting with an easy to use "Calibrate" feature.
I suspect this is your problem.
