Orochi V2 Minimizing Warzone

I have a strange problem. I played 85 hours of Days Gone with the Orochi V2 and had no problems. Then I switch to Warzone with the start of Season 4 and suddenly I encounter a problem - after a few minutes of play the game minimizes to desktop. When I play with my wired Viper 8K it does not happen, I can play for hours, but as soon as I play with the Orochi V2 within a few minutes the game will minimize to the desktop and I have to click on it to continue playing after which it never does it again until I relaunch the game. I have moved the wireless dongle to various USB ports (USB 2.0 and USB 3.0) and updated the firmware on the mouse to the latest version to no avail. The mouse works perfectly, I don't encounter any stutter etc., it's just this problem in Warzone that baffles me.
