Hello,
I have a problem when I want to play games in full-screen. Every time when I try it, the game automatically minimize at the start. When I try to open it, it kicks me out like pressing (alt + tab). It feels like when I open it, the game loses the focus. I have no problems with borderless window. I am using a GTX 1080 and Windows 10. I found out that DisplayFusion is the problem. Do you know how to fix it?

Here is an example of the problem:

Has no one an idea?

No, not really.

I have the same problem in apex legends, will try the above proposed solution tomorrow, regardless, I don't want to have to press a key combination every time I open a fullscreen application.

I tried it but it doesn't work. The game minimize when I start the game, so I have no chance.
