I've sort of experienced that in star citizen... sort of.
You can look down and see them, but they're not egregiously large.
Though one of the funniest bugs (feature?) will only happen if you play
with a female avatar: if you lay down in a bed, and then open up your mobiglass (in-game arm-tablet-thing) the UI lands about halfway through your breasts. It's like your character places their arm on their stomach, and the UI is projected forwards towards their face.
If I remember to I can take a screen cap of when it happened to me the other day on stream.
