Not possible for me, but I can try to describe it better:
Chrome is the main focused window. What's being done on chrome varies.
I hear a spinup noise from the case briefly and then Chrome loses focus as if another window has focus. I ignored it for quite awhile but decided to finally look into it and ran the focus.exe from hxxp://www.happydroid.com/focus and had it open on the second monitor, eventually the situation happened again and when I checked to see what was getting focus it was egui.exe except there was no popup visible anywhere and the main window was also not displayed anywhere.
