I am running a dual monitor setup with the Primary Monitor on the right.
In Windows, pressing + Shift + ← (or →) will attempt to move the current application to the appropriate monitor.
When I do this with Civ VI, the game moves to the Secondary monitor just fine... but then I am unable to navigate menus or interact with the game in any way. Moving the game back to the Primary monitor (via the same keyboard shortcut) fixes these issues.
What is going wrong here? I'd like to run Civ VI on a secondary monitor without completing retooling my Windows display settings. (I ran into an identical issue the last time I played Civ: BE, so I'm not sure if it's something specific to those games, something specific to Firaxis games, or an unlikely coincidence)
