Thank you. It feels good to be not alone with this. I will give some more information (hope this is not too much...) comparing GC3 and GC4.
GC3: standard view 4 and zoom out until symbols appear. GC4: standard view 5 and zoom out until symbols appear.
Hexes from top to down: GC3 = 25, GC4 = 68! This is a factor of 2,72!

And a shot of max zoom w/o symbols.
