It's almost 2018. Why is the "Mouse cursor out of screen" bug not fixed yet?

[Rysa]

Ths is unbearable and happens litteraly like 10 times a day. I'm in the middle of my rotation when all of sudden my mouse cursor goes out to my 2nd screen and the focus on the game is lost. It's been here since Closed Beta, reported by hundreds of people for years now and it is still not fixed. So yeah, what the hell NCSoft?

What i ma forced to do is to hit twice the Windows key each time i zone to refocus on the game.
