Can barely move my mouse when not in-game

I can’t explain why this is happening, but I can barely move my mouse when not in game. It’s almost unresponsive. Starcraft is the only application where this phenomenon exists and it only seems to happen when I’m not in-game. I have to make MAJOR mouse movements just to move a few pixels on the screen. It’s really bad. Tried with and without Razer Synapse software running just to rule that out.
