Not sure what to make of this… noticed this bug today when on a route in the A320.
Hard to explain the the cabin lights don’t seem to work unless the camera is doing somewhere around Mach Jesus near the aircraft. I would let the video explain but I can’t convert the file into one that’s allowed so you’ll have to use your imagination:
Moving camera fast:
Moving camera slow /not at all:
As a side note I should mention that I did try moving the camera about half an hour later to see if the time of day had an effect but the issue was still the same.
