M65 Pro bug?

I have a really weird vibe going on atm where by various times throughout a play session the mouse will just go nuts. The game will start firing my weapon as if im holding down left click, however the left click itself is not stuck or jammed. I have the rear button on the side set to the F key for my melees which will continuously spam F into any text field, in game, on chrome, dosent matter until i log out of windows, even unplugging it will not stop it only logging out or restarting. and finally, this seems to happen on overwatch mostly due to the quick movements that aren't required on most of the other games i play but it'll just spin me round, force my view to the floor and kinda jam like that until i raise my mouse off the mat and place it back down... The mouse is 4 weeks old, no spillages or droppages and hasnt left my desk since arriving. I've done the surface calibration, checked for updated firmware and CUE is up to date, any ideas??

Huh, I actually had that happen to me a few times while playing a few FPS - thought maybe the button was stuck or something. With the recent unresolved keyboard issue I had/that, I'm hoping this K55/M65 Pro combo lasts, otherwise it's bye bye Corsair.
