Is it just the window's own tile?

[unid15]

Yes, only the window's tile is blocked

[Killette2]

It's called a one way window for a reason, otherwise it'd just be a window

[Exxion]

This is because the secret repo was never updated, by the way

Now it has been, so they shouldn't be calculated for ghosts.
The comment says it also stops calculation for x-ray vision, but I see no code to suggest that's actually the case, so I'll leave this open
