Ion Slide content text behaviour

I know it’s not a big deal but when i’m using <ion-slides> with flip effect… after entering each slide the text goes from the default font color to the one i used on CSS. --ion-text-color: #48494e;

slideOpts = {
    initialSlide: 0,
    effect: 'flip',
    zoom: false,
    roundLengths: true,
    speed: 400,
    centeredSlides: true

where flipOpts it’s the opts from the official doc. click to play, it’s a gif image

This only happens once, after each page refresh
