Solved, it was a css transition.
Putting a
.ls-bg {
opacity: 1 !important;
}
in custom.css solved everything
Hi, i tried different transitions and also created a new custom transition with a fade effect to see if the BLINK could be removed but i didn’t find a way to remove it.
The site is now beyond an htaccess, you can see it here
user: temp
pass: blink
as you will se when the transition end and the new slide is fully loaded it look like the slide is made half transparent for half a second, so the backgound is shown and look like a “blink”.
