I tried this just now, checking disable fullscreen optimization does nothing to help. The notifications option did not help either as every time I restarted the application the focus assist settings would go from off, back to priority only. This did however lead to a "fix". I had originally disabled focus assist in the windows settings, but had left other tabs turned on within the settings (see screenshot/attachment). After also disabling the "During these times", "When I'm duplicating my display", and "When I'm playing a game" options, I no longer dropout to desktop for more than a quarter of a second at best. Not entirely fixed but I went from waiting 5-10 seconds at the desktop and flashing in and out, to a quick .25 sec flash back into the loading screen and or the map already. http://i16.photobucket.com/albums/b19/rv8080/focus%20example_zpspgk24gkt.jpg
