Let me give you guys a little backstory I've been using the Corsair M65 for almost a year but it started to have some problems so I bought the g303 Now the problem with the g303 I mainly play csgo so its the first game I tested the g303 in and I realized when I move the mouse left and right on my mouse pad my crosshair moves up and down Example https://www.youtube.com/watch?v=tCl7gP1d_jk now the M65 doesn't do this example https://www.youtube.com/watch?v=hGhCEy8VmoU If anyone could help me fix the g303 so it doesnt do that I would much appreciated it (My writing skills arent very good sorry if something doesnt make sense)
