OblivionageNot_MatlockClean your mousepad off and spray the sensor lightly with compressed air.
My mouse (R.A.T.7) does the same thing occasionally and it usually goes away for a bit after I clean it.
yeah but he says it happened to him after an update so i don't think that's it.
It happened after that one update when people started complaining about fps problems, but my fps hasn't been considerably worse or anything
