I am currently using deathadder v2 mouse, and the mouse pad is Invicta Gaming Mouse Pad. Usually, when the mouse scratches the mouse pad, it is because dust or hair stuck near the mouse feet. However, I checked the corners and cleaned the mouse feet and mouse pad, but it still scratches the mouse pad. I placed the mouse on my thigh and could not feel anything sharp. Everything was smooth but it just still scratches the mouse pad. I intentionally moved the mouse hard and attempted to find another scratch spot on the mouse but there isn't any. The mouse pad is a hard mouse pad.

Any tip and trick to help me identify where the issue is? It is so hilariously dumb.
