When transitioning from screen to screen (opening video, first menu screen, starting video, character creator), the screen will just go black, sometimes my monitor will tell me there's no signal detected, sometimes it comes back, sometimes it comes back when I alt-tab in and out, sometimes I'm just stuck with a black screen. Normally switching to borderless window (which I guess is called fake full screen in your game?) fixes this kind of problem in other games, but it still seems to be trying to render full screen.
