Invisible Mouse

This is still an issue, it's happen to me twice this week where I get into a game and my mouse disappears. No one can play with an invisible mouse, not to mention I have to deal with my entire team flaming me for 40 minutes. I cant leave or I get reported, I cant contribute to my team, and I'm stuck playing a game that I really cant play for 40 minutes...

I have looked to fix this issue on my own on other forums but it is not an issue with my computer or my mouse, it's an in-game issue. Please fix this
