Not to be a hair in the soup of my own praise (I've already posted a mention with screenshot at some point, so sorry if this is redundant), but I was already capturing this, and it perfectly demonstrates a bug in the gravitational lensing effect of black holes; it does not apply to light from supernovae.
Video is unlisted, so can only be viewed with a direct link:
Edit: Another bug connected to gravitational lensing: Sudden switches
Anyway, still very satisfied with the current version; all praise is due to the dev team.
