No. It's not implemented by the underlying xserver. It's the same
software cursor code that kdrive and (I guess) also Xorg is using. Xglx
is creating an invisible cursor when the software cursor should be used
just so that we don't get two cursors, that might be what's confusing
you...

You don't have to do that.
