Mathjax: Hide Math Expression While Processing

Im developing an application that shows a mathematical expression in function of the content of a form. The webpage show the different states of the expression while its rendering,

Solution 1:

You want to turn off preprocessor previews and the fast previews. Try setting your configuration to this

  MathJax.Hub.Config({
    "fast-preview": {disabled:true},
    tex2jax: {
      preview: "none",
      inlineMath: [["$","$"],["\\(","\\)"]]
    }
  });

This should make things work a bit more like what you want.
