I’ve come across similar threads about the same exact model mouse I have here, and it doesn’t look like good news. My Razer DeathAdder V2 X Hyperspeed seems to be failing by exhibiting a very slow creep towards the upper left of the screen. It is otherwise unresponsive, except for maybe a few clicks that may register here and there.

I have tried replacing the battery, cleaning it, updating Synapse software and drivers, and using it on a different PC, but it still exhibits the same behavior. It is being used atop a clean Razer Gigantus mousepad.

Are there any other remedies to attempt, or is it done?
