MacOs Window Mode doesn't work on League

Hello,

So this issue has been happening forever. When you set the league game screen as a window, the cursor goes off the screen if you move it too fast. This issue makes me change screens/create new folders on my desktop and messes the gameplay in general...

Please riot, get this fixed asap, I've got a new monitor which is quite big and I cannot play League there because it is too big to play full screen and window mode is not an option due to this bug and performance. The same happens on borderless btw.
