So my issue is when i try alt-tab in D2 it sometimes works yeah but that comes to my 2nd monitor where i can switch between desktop/discord what im using when i play. so displayfusion thinks my MAIN is 2nd monitor left or dont know why. i cant even see that alt tab thing only screen flickers between these two.

however displayfusion works very well when im browsing or do something else and in fortnite it works great but one game where i notice that issue is destiny 2..

//EDIT: Working others resolution but no fullscreen shame.. i do not want to play windowed full screen bc that issue :/
