What happened to world displacement and tesselation?

I’m getting all kinds of weird behaviors, the displaced mesh is at a different scale than the actual texture map it’s using (if I use the same output for world displacement and base color, I get two different things, which makes no sense) and also as I move the camera, my displacement changes as well.

Is this a bug?

for anyone with the same problem, just uncheck “crack free displacement”. that’s what broke it up, doesn’t let the displacement map tile along with the other maps.
