Hello there, the last couple of days I've been having issues while in the game where my mouse will make an erratic jump in a random direction. It can be the opposite way I am attempting to move my mouse or it will go further then intended. I have a very cheap logitech mouse that has had no problems until the last twenty four hours and the bug is only occurring during League of Legends gameplay, no other games appear to be having this problem.
I have had this problem before also but it was definatly the mouse. 80$ corsair mouse still gives me problems at times. I would check to blow out the laser on your mouse or clean the bottom of the mouse and mouse pad, specially if you eat at your PC. I often times just need to unplug and re plug in my mouse if it gets out of control and it always fixes the problem for a few days at least :)
Depends, if it is a soft pad with a rubber bottom I wouldnt reccomend it as a dryer gets very hot could melt the rubber. I use a hard mouse pad so a nice damp cloth clean worked best for me but you could always even vacuum a fabric one or give it a wet cloth wipe and let it air dry.
