The map misses a decent amount of information at first, looks like this:

It should show:

• NPC Faction territory
• Player Faction territory
• 3 axis of the galaxy itself
• highlighted gridlines of the selected system
• the coloured faces (blue, red, green) of the selected system

As far as I can see, most of the missing stuff is just rendered pure black.
Even in explored territory, the grid lines appear black when they should be white.
