In google maps version 3.14 there are some new css rules added for the custom infowindow. I use the infobox plugin and now many of my elements styles are overwritten.

Since Google changed the behavior of older versions it wont work anymore to load v1.13. The new styles and roboto-font will always load. My new solution is to save every stylesheet into a separate file and include the following script:
google.maps.event.addListener(map, 'idle', function()
{
$('style').remove();
});
This will remove every style-tag written by googles api and keeps your own style save but the roboto font will still be loaded. I don't see any way to stop that.
