random behavior of Pitch Wheel & Mod Wheel

[tonnith]

For some reason the Pitch Wheel & Mod Wheel give random behavior. When i turn the pitch there is a lag in response, and for some reason the pitch changes randomly. The same happens with the mod wheel 

I think this started occurring after the latest firmware upgrade but i'm not 100% sure.

Did you recalibrate the flippers after the update as instructed? Try doing that and see if it fixes it.
