user30068: I have a few vector layers that are parent to Null Object. If I apply Rough Edges or Turbulant Displace to any of these layers, and then animate the scale on my Null, my layers begin to move/flow/leak.
What is the problem and how can I fix it?
I want them to remain static after applying the effects.

user4426: I think it's because the Roughen Edges effect is a pixel-based effect applied to the entire display of your comp.  If you pre-comp the effect first, it won't display the animating edges.
Or you could try applying this expression to the Roughen Edges offset (transform) property, as explained here:
parent.position * 400 / effect(“Roughen Edges”)(“Scale”)
