Gallery Slideshow Transitions

Site URL: https://brianrolfe.co.uk/main-home

Is there any way to adjust the transitions on the 7.1 gallery simple slideshow? On version 7 it used to be far smoother but seems very abrupt and jerky on 7.1. Easing code snippet?

Add to Design > Custom CSS

.gallery-fullscreen-slideshow-item-img{
	transition: opacity 1600ms ease-in-out !important;
	-webkit-transition: opacity 1600ms ease-in-out !important;
	-ms-transition: opacity 1600ms ease-in-out !important;
	-moz-transition: opacity 1600ms ease-in-out !important;
	-o-transition: opacity 1600ms ease-in-out !important;
}

//.gallery-fullscreen-slideshow[data-transition="fade"] 
.gallery-fullscreen-slideshow-item[data-active="true"] .gallery-fullscreen-slideshow-item-src{
	transition: opacity 1400ms ease-in-out !important;
	-webkit-transition: opacity 1400ms ease-in-out !important;
	-ms-transition: opacity 1400ms ease-in-out !important;
	-moz-transition: opacity 1400ms ease-in-out !important;
	-o-transition: opacity 1400ms ease-in-out !important;
