I have an intellioptical mouse and for some weird reason I get this weird glitch where my crosshair will move in the direction I was turning my mouse depending on how fast I am flicking the mouse. I've tried in many other games and it is only in CS:GO that this problem occurs in. My friend even saw it but has no idea what it could be because like I said the cursor never does this in any other games. I've tried reinstalling, verifying integrity of the game files and such. Not sure what to do as this point because to me it seems like a CS issue rather than a mouse issue.
