if you are playing regular set up try changing to tactical i have had the same problem due to pushing down on stick very slightly while pulling RT ihave found some controllers worse than others i had one controller( not a viking ) which didnt do this then started and became worse over time i think it is a problem with certain sticks wearing in and becoming more sensitive, perhaps someone with more technical knowledge would know, if that is the problem on tactical you end up with a drop shot instead of a frustating death hope this helps
