Take a look at the message window:

Warning: The maximum gradient found was 2.381, but max_gradient of the
isosurface was set to 1.100. The isosurface may contain holes!
Adjust max_gradient to get a proper rendering of the isosurface.

If you add max_gradient 2.4 to your (pow(x,2)+y) isosurface, it'll work.

Hmm, the sphere problem looks like a problem with PinkAlabaster.... checks
textures.inc.... Ah-ha!

(from textures.inc)

// Gray-pink alabaster or marble.  Layers are scaled for a unit object
// and relative to each other.
// NOTE: This texture has very tiny dark blue specks that are often
//       mistaken for rendering errors.  They are not errors.  Just a
//       strange texture design.
