I have a problem with my dual monitor setup. I have a 144hz and a 60hz monitor. When I open a game on my main monitor (in my case Fortnite) and then click on my 2Monitor it briefly turns black and my mouse is "teleported" back to the main monitor. If I press my 2Monitor now it reacts first. (The same is also when I'm first on my 2Monitor and then go back to my main monitor).
