I've had this happen a couple of times recently on RF2 (Intel I7/Win10/AMD R9380 no overclock/G27/3 screens/Eyefinity/latest Mills track/Eve F3 cars). Suddenly, mid-race the game will minimize to the taskbar. Everything keeps running because you hear the sounds (especially of my car slamming into a wall) and it all returns to normal when the RF2 icon is clicked. This has happened several times, but, of course, not always and not reproducible. Has anyone else seen this behavior?
