Alt + tabbing onto the leagues window usually works for me if needed. I can still move my champ etc, it is just that when I move my cursor to the side of my screen where my second monitor connects, instead of staying inside LoL, it moves to the second screen. Yea mines done that a few times.
go into your windows mouse settings and pick/upload a mouse that you think would be better, then set it as your default mouse. then in league settings turn the cursor off. OP is talking about in-game cursor, not the client one. yeah i know this works for ingame cause im p sure there is an option to use ur real mouse.
Change Cursor Size and Color in Windows 11. Right-click the Start button and select Settings . Press Accessibility on the left-hand menu then navigate to Mouse pointer and touch . Under Mouse Pointer Style, select the cursor color you would like. You should have the choice between white, black, inverted, or custom color.
