Rounded corners in safari/chrome are not rounded on hover for first second

Question

I have a problem with Safari/Chrome. On these browsers ( on hover ) my rounded corners make a square and then go back to be rounded.Here is the code

CSS
    div.img-cont {
            float:left; 
            position:relative; 
            margin:10px 20px 0 0px;
            width:180px; 
            height:160px;    
            border:0px solid #FFF;
            overflow:hidden !important;
             -webkit-border-radius:5px; 
                -moz-border-radius:5px; 
                 -ms-border-radius:5px;
                  -o-border-radius:5px; 
                     border-radius:5px;            
    } 
    div.img-zoom { 
            float:left; 
            position:relative; 
            margin:-20px 0 0 -20px; 
            width:220px; 
            height:200px;
            background-position:center center !important;
            -webkit-transition: all 0.25s ease-in-out;
               -moz-transition: all 0.25s ease-in-out;
                -ms-transition: all 0.25s ease-in-out;
                 -o-transition: all 0.25s ease-in-out;
                    transition: all 0.25s ease-in-out;
    } 
    .transition {
            -webkit-transform: scale(0.93,0.93); 
               -moz-transform: scale(0.93,0.93);
                -ms-transform: scale(0.93,0.93);
                 -o-transform: scale(0.93,0.93);
                    transform: scale(0.93,0.93);    
    } 
    .f_border{
             -webkit-border-radius:5px; 
                -moz-border-radius:5px; 
                 -ms-border-radius:5px;
                  -o-border-radius:5px; 
                     border-radius:5px;  
    }

HTML

       <div class="Box_1x1_front" style="height:180px; background:#eaeaea; ">
            <a class="leftAllPlace" rel="thumb" title="" href="http://bonavestis.pl/image/cache/data/Produkty/Sukienki/Sukienka%20JUST%20UNIQUE%20Bandażowa%20W%20Beżu%20+Złoto/Image001-885x885.jpg">
                <div class="img-cont f_border">
                    <div class="img-zoom img_2">
                        <div style="float:left; width:100%; height:100%; background-image:url('http://bonavestis.pl/image/cache/data/Produkty/Sukienki/Sukienka%20JUST%20UNIQUE%20Bandażowa%20W%20Beżu%20+Złoto/Image001-372x372.jpg');"></div>
                    </div>
                </div>
            </a>
        </div>

JAVASCRIPT HERE

    <script>
    $(document).ready(function(){
        $('.img_2').hover(function() {
            $(this).addClass('transition');
        }, function() {
            $(this).removeClass('transition');
        });
    });
    </script>

Its like zoom out div with background-image inside div with rounded corners Any ideas how to fix this...

Answer 1

1)

As @Squideyes mentioned there is an only-CSS approach how to add a transition.

Just add CSS selector:

.img_2:hover {

}

instead of .transition

2)

Also I recommend using <img> instead of background-images of <div> in your case because from my point of view image here is a content-part element and assumes using <img>.

More info: IMG vs background-image

3)

And about the scale problem in Chrome. Seems that there is a glitch with transition and border-radious in Webkit. Try to change width and height instead as a workaround.
