Full screen option broken - impossible to change resolution

[Hyanoa]

Hello,

I have recently installed Civ VI in my new Windows 11 PC. I have just loaded the game but the full screen option does not properly work when changing the game resolution, and I do not figure why. I made a quick search but did not find anything.

When I try to change the game resolution to a lower resolution (in order to "zoom" the game compared to the size of my screen and better see the game) in full screen, the game in fact reduces the size of the "window" of the game up to the new resolution, as it was not in full screen but in window mod. Consequently,

I tried to change parameters but it does not change anything. The problem occurs whether with DX11 or DX12 launching option.

Thanks in advance

P.S.: Behold a screen picture of the problem, where we can see that the game reduce the full screen "window" and let see the other softwares/desktop opened
