[BUG / HACK ????] Mouse that literrally gets STUCK everytime I try to fight an ennemy champion.

Bonjour, Hi there !

During a ranked 5v5 game of this 5.14 patch, I discovered a really weird bug. Everytime I hit an ennemy champion in my game, my mouse did bug, getting stuck, almost not moving, like if it was controlled or blocked by a third party program (hacking suspision???)

After some really easy kills missed because I couldn't follow, and some kills given because I couldn't move, I decided to register my screen vision (my mates were going crazy about me, thinking I was just saying b******t after dying).

I played a dozen of games today and I only had this problem on ONE ranked game. During that game, I restarted the game itself, the client and everything, and I didn't get anykind of amelioration. I was the only one having those troubles there.

Does this issue remember something to somebody? Could it be any kind of bad action from ennemy team (#paranoïd)

Thanks to you all.
