Hello!
Sorry I don't have links to show the issue as I currently work on this project offline. I have this owl crarousel 2 on the front page and a Understrap based website.
The issue appears from time to time, not sure exactly when or why but depends on the width of the browser. So the issue is there is a 1px line on the left of the current picture displaying the border of the previous picture. All pics have same size.
<div class="fadeOut owl-carousel front">
<div class="item">
<a href="http://elsphere:8888/"><img src="http://elsphere:8888/wp-content/uploads/2016/11/frontslide-01.jpg"></a></div>
<div class="item">
<a href="http://elsphere:8888/"><img src="http://elsphere:8888/wp-content/uploads/2016/11/frontslide-03.jpg"></a></div>
<div class="item">

</div>
owl-carousel.front{
max-width: 1246px;
margin: 0 auto;
margin-bottom: 22px;}
div#page-wrapper.wrapper{padding:0 0 32px 0;}
Query(document).ready(function() {
var owl = jQuery('.owl-carousel');
owl.owlCarousel({
items:(understrap_slider_variables.items),
loop:true,
autoplay:true,
autoplayTimeout:(understrap_slider_variables.timeout),
animateOut: 'fadeOut',
animateIn: 'fadeIn',
nav: false,
dots: true,
autoplayHoverPause:true,
margin:0,
});
jQuery('.play').on('click',function(){
owl.trigger('autoplay.play.owl',[1000])
});
jQuery('.stop').on('click',function(){
owl.trigger('autoplay.stop.owl')
});
});

Ok! I managed to fix that issue by changing the margin from 0 to 1
I have this issue but I cannot add margin because I have several items shown at once.

I fixed it by changing the following line
https://github.com/OwlCarousel2/OwlCarousel2/blob/develop/src/js/owl.carousel.js#L891
to
transform: 'translate3d(' + (coordinate-1) + 'px,0px,0px)',
@lmanzurv with this solution I get the line from the next picture on the right side if I have a tablet/mobile viewport. Guess I have to fix this with the margin approach.
This problem, in Safari browser (1px https://duvils.ru).
Please help to solve this problem (version owl 2.2.0)
(Sorry about the canned reply.)
We have received your feature request and will evaluate the implementation of this.
I can't give you an estimated date when or if this will be integrated into the project. This might happen when the main refactoring will take place.
.owl-item .item {
margin-left: 1px !important;
}
It worked for me.
I have this problem also
I faced this problem when the grid was based on flexbox and the parent (owl-stage or owl-stage-outer) had pseudo elements :before and :after. Hello bootstrap 3 馃く, just remove them.
Issue still valid.
I fixed it changing line 299 of owl.carousel.js to:
let width = (Math.ceil(this.width()) / this.settings.items).toFixed(0) - this.settings.margin,
you can solve this with simple CSS:
.owl-stage-outer::after {
width: 1px;
content: " ";
position: absolute;
top: 0;
left: 0;
height: 100%;
background-color: white;
}
I put the margin: 1 to the options and it works fine. Possibly need more. When I tried this https://github.com/OwlCarousel2/OwlCarousel2/issues/1647#issuecomment-422793514 the first slider was skipped)
I got 1px extra line but on the right side of every image. The margin:0 didn't do the trick for me,
I fixed in CSS by removing the 'dot' in content: ".";
.owl-carousel .owl-stage:after {
content: ".";
display: block;
clear: both;
visibility: hidden;
line-height: 0;
height: 0;
}
In the owl.carousel.js file
REPLACE
transform: 'translate3d(' + coordinate + 'px,0px,0px)'
WITH
transform: 'translate3d(' + (coordinate-1) + 'px,0px,0px)'
And, in case of the owl.carousel.min.js file
REPLACE
transform: 'translate3d("+b+"px,0px,0px)'
WITH
transform: 'translate3d("+(b-1)+"px,0px,0px)'
Hope this helps!
