I have the same thing on xbox, its not only in challenges. Any kind of adjustment needed with analog stick in settings, just shoots the presetting out of whack, like marker colors and such. When trying to host a portal, it pulls the menu up constantly, you have to hold analog down, then use D-pad just to navigate the menu.
It is also affects the Tank and IFV treads, if sitting still, it wants to drift the vehicle into movement, specifically turning it, very obvious with the IFV.
Selecting spawn locations becomes a battle with the cross, just to go where you want.
I tried 2 other controllers and still affects it, even bumped the dead zone in settings up, makes no difference. None of my controllers have drift issues.
