At certain points during the UI for surveying a planet, there's a flicker of motion in the corner of the screen - the radar UI appearing for a brief moment, then moving down and off-screen.
This would probably look pretty good for cases where the radar UI had previously been visible, but... in this context, it wasn't, which makes the whole transition look wrong.
Sequence of events: Interact with planet. Radar UI is hidden. Select 'perform survey'; radar UI is very briefly un-hidden. Select 'leave [Q]' (instead of 'perform survey [G]'), and you're returned to the initial planet interaction - this transition works correctly, with no space UI flashing into existence. Select 'perform survey' again, and you can see the glitch again.
This also happens when going from planet interaction into looting ruins, though that particular transition can't be done more than once.
