Meta slider – does not display full width in beginning

vantage premium 2.4.4, meta slider 3.3.7.
If my page loads and slider pops up, there is wide margin on the left side for few sec and then slider jumps to full width. In settings in activated full width and stretch option. I also added to css to reduce that
.metaslider img {
min-width: 98vw;
margin: 0 auto;
}

But it still exist and does not look nice. Any idea, how to get it to display full width from beginning.
