Debug your CSS for Ghost CSS Elements.

Use this bookmark to debug your CSS: https://blog.wernull.com/2013/04/debug-ghost-css-elements-causing-unwanted-scrolling/

Or add the CSS directly yourself:

* {
  background: #000 !important;
  color: #0f0 !important;
  outline: solid #f00 1px !important;
}

In my case a Facebook Like Button caused the problem.
