Toggle Grid on/off

[melnibonian]

Hello

I don't know if this is the correct place to ask this question so if it is in the wrong place I apologise and please feel free to move it accordingly.

The Hotkey ctrl-g is supposed to toggle the hexes on and off on the map. Nevertheless when the hexes are toggled off they are still visible on the map, especially on maximum zoom-out. Any way to work around this? Am I making a mistake somewhere?

Thank you very much in advance
