JoyCon stick strange behaviour

[millski]

Hello all,

I have a joy con stick connected to a Circuit Sword and it's working but at the extremes of movement it is giving secondary input. So if gently pushing up on the stick it moves up. Push the stick all the way up and it moves up and right. Same issue with other directions.
Is there a setting somewhere to reduce the sensitivity of the stick at the extremes of movement? in mupen64 there are analogdeadzone and analogpeak settings but I can't seem to eradicate the problem with them. I've no idea if there's anywhere else in the configs these can be altered?

Maybe something to do with the already known "joycon drift"?

Just have a look in the internet about it... Ok drifting and moving to another direction are not exactly the same buy maybe this helps your problem solving.
