If you have an inline logo, te menu bar jumps on scroll and there is too much padding at the top. Fix with this css.

/* START Fix primary menu logo jump */
@media only screen and (min-width: 981px) {
    .et_header_style_split #main-header.et-fixed-header .centered-inline-logo-wrap {
        margin-top: -33px !important;
    }
	.et_header_style_split #et-top-navigation{
		padding-top: 50px !important;
	}
}
/* END Fix primary menu logo jump */
