I faced the same problem, if you resize that iframe or the div where responsive file manager is, then thumbnails will show up...

Work around:

• set iframe height/width to be 101%
• set onLoad attribute to iframe that will resize iframe width/height to 100%

Example:

<script>
function loadThumbs() {
    var rfm = document.getElementById("rfm");
    rfm.style.height = "100%"
}
</script>
<iframe id="rfm" onload="loadThumbs()" src="..." style="height: 101%; width: 100%;" />

I've finally found full solution: It's all because of $lazy_loading_enabled variable. On first load it is true. In dialog.php line 621 just set its value to false

$lazy_loading_enabled = false;

Now it should work. Hope this was helpful.
