Is your BaseCamp 4.8.7 displaying 3D maps incorrectly?

I just upgraded to BaseCamp 4.8.7 on my MacBook Pro running Catalina (10.15.1). 

My 3D map no longer uses the entire area set aside for displaying the map. Rather, it is a smaller representation in the lower left part of the display area.

Is anyone else experiencing this? Any solutions?
