Question

On my page I have an element with the following CSS rules:

.pointer {
    position: fixed;
    background-repeat: no-repeat;
    background-position: center;
    top: 70%;
    z-index: 1;
    width: 3%;
    height: 6%;
    text-indent: 100%;
    white-space: nowrap;
    overflow: hidden;
    float: left;
    left: 0;
    background-image: url("img/myImage.jpg");
}

Works good in the browsers I tested, only Opera does not like it. When I scroll, the background image also gets “scrolled” and therefore disappears as is gets out of the container.
I believe that is a known problem, but still I wasn’t able to find a solution.

On this page a method is described how to hide CSS rules from Opera, but besides the fact that this post is anno 2002, I actually don’t want to use CSS hacks.

Removing overflow: hidden does not fix it, adding background-attachment: fixed didn’t help either. Any other ideas or solutions?

I have taken a look at your fiddle project. I believe that the problem is caused by having the background image and border radius applied to the same element, I honestly can’t explain why this only happens in opera.

But a simple solution is to wrap the anchor in a div and split the styling between each, ensuring that the background image and radius are on separate elements.

I have created a fiddle with a possible solution, it needs some tidying up but I think it will get you on track – http://jsfiddle.net/zyj6Z

The CSS is below:

.link {
-ms-filter:"progid:DXImageTransform.Microsoft.gradient(startColorstr=#4d000000, endColorstr=#4d000000)";
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#4d000000, endColorstr=#4d000000);
zoom: 1;
background-image: url("data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIxNiIgaGVpZ2h0PSIxNiI+PHBvbHlnb24gZmlsbD0iI2ZmZiIgcG9pbnRzPSIyLjc2OSw3Ljk5MiAxMC43NjIsMCAxMy4xMzIsMi4zNjIgNy42MDQsNy44OTkgMTMuMjMxLDEzLjUyOCAxMC43NjIsMTYgMi43NjksOC4wMDcgMi43NzYsOCIvPjwvc3ZnPg==");
background-position: center;
background-repeat: no-repeat;
width: 10%;
height: 10%;
position: fixed;
top: 70%;
left: 0;
}
.test {
width: 10%;
height: 10%;
position: fixed;
top: 70%;
left: 0;
-webkit-background-clip: padding-box;
-moz-background-clip: padding;
background-clip: padding-box;
overflow: hidden;
-webkit-border-radius: 0 5px 5px 0;
-moz-border-radius: 0 5px 5px 0;
border-radius: 0 5px 5px 0;
background-color: #000000;
background-color: transparent\9;
background-color: rgba(0, 0, 0, 0.3);
text-indent: 100%;
white-space: nowrap;
}

and HTML here:

<div class="outer">
<div class="wrap">
     <h1>Stuff</h1>

    <div class="test"> 
        <a href="#" class="link">Hide me!</a>
    </div>
    <ul>
        <li>
            <img src="//placehold.it/150x150" />
        </li>
        <li>
            <img src="//placehold.it/150x150" />
        </li>
        <li>
            <img src="//placehold.it/150x150" />
        </li>
        <li>
            <img src="//placehold.it/150x150" />
        </li>
        <li>
            <img src="//placehold.it/150x150" />
        </li>
        <li>
            <img src="//placehold.it/150x150" />
        </li>
        <li>
            <img src="//placehold.it/150x150" />
        </li>
        <li>
            <img src="//placehold.it/150x150" />
        </li>
        <li>
            <img src="//placehold.it/150x150" />
        </li>
    </ul>
</div>

I hope this helps.
