Illustrator graphics become blurred when pre-composite

When you use collapse transformations, it changes the render order for affected comps and layers. Instead of rendering the inner layers of a precomp inside the precomp, then rendering the precomp itself as a layer with the main containing comp, collapse transformations basically pulls the precomp's layers into the main comp and then applies any transforms/effects done to the precomp layer itself directly and individually to all its contained layers.

As you've noted, this can have a really drastic and perhaps unexpected result.

Your simplest solution here is probably to scale up in the precomp to the maximum size you'll need and leave collapse transformations off.
