1px loading progress bar at bottom...Can be disabled?

1px loading progress bar at bottom...Can be disabled?

When I change page using the following code.
$.mobile.pageContainer.pagecontainer("change", 'products.html', { role: "page", reloadPage: true, allowSamePageTransition: true});

There is a little progress bar at bottom (I think it is 1px height).

Is there any way to hide it/disable it?

Thanks.
