The infamous left click bug

I dont know how this happens but randomly in games you will have to double left click if not quadruple left click. Its not just me who has it though, a friend of mine gets it sometimes as well. However my other friends who use PC dont get this. Riot im asking you to look into this bug because the only way of solving the bug is to leave and reconnect (which the bug also makes it so even if you have 4 ping it will take around 3 min) which hurts in ranked bc: you will still lose lp even if you reconnect and win the game. This bug as been in the game for about 2 years. Fix this plz
