Bug Report [GAMEPLAY], [CLIENT], Multi Monitor Mouse Cursor

I am using a 3 monitor setup and have an issue with my mouse curser leaving the league screen making the game unplayable. This is happening every time I play and I have only manage dto fix it with third party software.

On both borderless and Fullscreen mode when I League my mouse curser leaves the screen.

If anyone else is getting this issue I would recommend that you download dual monitor tools and using the lock curser to screen setting.
