Hello, I think there is less friction between the mouse mat and the desk. Have you tried putting a cardboard or a plain paper below the mat. That could solve your problem as it worked for me. Please reply.
I have this exact same setup. To the TEE. I even bought the 2013 razer naga thinking it was a tracking issue with the mouse. Problem was still there. I used a piece of cardboard cut to the exact size of the mat and the issue went away. I've been using it 3 weeks since I did this with no issue.
