With the proper game options active, when a city reaches a high level of culture, its workable radius expands to 3. Great mechanic, I love it, there's just one problem: I can't control the upper three tiles of the expanded radius, as they fall under the city food and production bars. Even if some pixels of the white circles actually are out of the green border, clicking on those few pixels does nothing. See screenshot. So how can I change the zoom in the city screen? I tried minimizing or hiding the interface, but that does not work in the City Screen. The lower three tiles work as intended, as even if under the defending units' icons, they are still accessible.
