Hi, xdpyinfo doesn't return any information about Z buffer bits. Are
you referring to this:

         visual:
              visual id: 0xa4
              class: TrueColor
              depth: 30 planes

That doesn't mean the depth buffer has 30 bits; that means the depth of the
color buffer is 30 bits.

There are no visuals on iR with 30 bits of Z.
