non-VR gaming when using 'desktop mirror' mode after SteamVR 2.0 update
Since the SteamVR 2.0 update, when launching a non-VR application from Steam Library a theater screen from Steam will be displayed automatically inside VHT, over the already existing desktop screens from VHT.
You can deactivate this feature from Steam by changing the steam settings as:
set 'SteamVR Setting->Advanced Settings' to Show
set 'SteamVR Setting->Dashboard->Present Non-VR Application on Theater Screen Upon Launch' to Off
