When I turn on the panel light on the left side of the captains seat half the cockpit becomes invisible and i can see through the floor and onto the ground, Also I have the 767 V1 but i believe the current version is 1.5 I would like to update but the only one I have available is V1 any help would be amazing thanks.

Just downloaded and installed that update of the link you gave me nothing changed this is my issue. When I try to turn the panel lights up the sea and yoke and floor become invisible meaning I can see the ground.
