After clicking team switch there is an option to choose an available unit to view. When you click this option the camera will travel and zoom to the selected unit. However the map giving the location of the unit remains on the screen and then obscures the 3D view of the unit and much of the area surrounding him.

Either increase the alpha of the map during this period, shrink map to a corner, allow the map to be dragged around or dispense with the map entirely during this option.
