Not the wingtip vortices, but prop wash vortices. On very humid days, we

I've seen that as well, but it's visible from every angle. It's
essentially a small cloud created at the tip of the prop.

This was absolutely invisble unless you were centered behind it. Then
you got a distorted view of everything through it. It wasn't white,
it was clear.
