Hello folks, I'm having this issue and it's very frustrating 😭
I'm using 2 screens and when playing in full screen, windowed, borderless, whatever, the mouse cursor always goes out of the game monitor and ends up on the second. It doesn't happen if I'm in the menu of the game, only when playing, which makes it impossible to fight for example. The mouse goes to the second screen and I start clicking on icons, or whatever is there. Sometimes opens after-effects in the middle of a battle by accident. it's really annoying. I can't find a way to solve this unless installing software. Has anyone has had this same problem? did you find a solution?
My only solution right now is to off-set the screens but still happens now and again.
