IE8 CSS Relative position extra whitespace

Question

I'm facing a problem that I couldn't solve, When I add Position:relative; to a div it appears with sorta a white border, or extra space like in the image

and if I remove Position:relative; border moves to the parent which also has Position:relative; and this is only on IE8. Markup:

<div class="content clearfix">
    Some content goes here
         <div class="block">
               <div class="block_content" style="display: block;">
                 Some content goes here
              </div>
          </div>
 </div>

CSS:

.content {
min-height: 100%;
height: 100%;
position: relative;
width:100%;
background-color:#ebebeb;
}
.block_content {
display:none;
position:relative;
margin: 25px 20px 15px 20px;
}
.block{
      overflow:hidden;
    width:58%;
    padding-bottom:60px;
float:right;
position:relative;
margin-right:10%;
background: rgb(222,222,222); /* Old browsers */
background: -moz-linear-gradient(top,  rgba(222,222,222,1) 0%, rgba(255,255,255,1) 0%, rgba(222,222,222,1) 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(222,222,222,1)), color-stop(0%,rgba(255,255,255,1)), color-stop(100%,rgba(222,222,222,1))); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top,  rgba(222,222,222,1) 0%,rgba(255,255,255,1) 0%,rgba(222,222,222,1) 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top,  rgba(222,222,222,1) 0%,rgba(255,255,255,1) 0%,rgba(222,222,222,1) 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(top,  rgba(222,222,222,1) 0%,rgba(255,255,255,1) 0%,rgba(222,222,222,1) 100%); /* IE10+ */
background: linear-gradient(to bottom,  rgba(222,222,222,1) 0%,rgba(255,255,255,1) 0%,rgba(222,222,222,1) 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#dedede', endColorstr='#dedede',GradientType=0 ); /* IE6-9 */

            box-shadow: 6px 6px 14px #333333;
        -moz-box-shadow:6px 6px 14px #333333;
    -webkit-box-shadow: 6px 6px 14px #333333;
    }

Well, well, well, I think I have what that strage border comes from.

It's from that piece:

.maroon:before {
    border: 4px solid #FFFFFF;
    bottom: 0;
    content: "";
    display: block;
    left: 0;
    position: absolute; 
    right: 0;
    top: 0;
    z-index: -1;
}

If you remove content:""; you don't see that border anymore.

Seems that IE8 it's making a mess with the parent. So, if you change parent position:relativeor remove it, IE8 apply this style to the previous relative element. I don't know if this might be for the filter you applied to achieve rotation and that stuff...

Sorry for the incomplete info, at least we can target where's the issue... I continue studying, but now perhaps you or other user, knowing this, can help to fix it.
