I haven't had this problem before that I can remember but it's happening every day now.
I'll be playing a game and all of a sudden it minimises the game and goes to the desktop.
Recently I was getting something similar where my mouse would stop working as the game lost focus but I just had to press something on the screen with the mouse so it stays in the game but most likely went into borderless.
EDIT: Just tried recording in BFV and this happened my video from that point on wards was a black screen. This is definitely a new issue I think with 19.1.1
This has happened with BFV, PUBG and just then DCS 2.5.
