I've had a further look and I'm still not sure whether it's bugged or not - it's also not VR specific as it's doing it in the flatscreen game as well.Well, not quite the same, but I have had several double-takes the last week or two, over the draw distance willing shadows from hangar structures into existence along with the landing pad's traversal, but couldn't say whether that is new, or it just never bothered me quite as much before...
I used to be rather annoyed with concourse interior shadows ceasing to draw, at a distance of a few paces, and assume my brain has simply incorporated that behaviour into its model of how the world works in Elite...
(I have also seen more than I am accustomed to, of entire mountain ranges strobing between day and night, when the light comes in low...)
It looks like certain objects (like hand-held data slates) have spot shadows drawn at a further distance but at the slow update rate we saw with the recent 'Peter Pan' shadows. Get closer and the NPC spot shadow kicks in but you can still see the slowly updating shadow underneath.
Here you can see the datapad shadow on the seat next to the left sitting-down NPC, before the spot shadows appear on them and the standing mission-giver to the right:
...and here you can see the datapad shadow on the bulkhead next to the seated NPC prior to my movement forward, which brings up spot shadows on the character and advert panel.
