Hi, Thanks for your detailed report. I can see that the CSS is not well aligned 
in the portal-example, but I don't see the "white frame" behaviour (Chrome, Mac 
OSX 10.6.8).

Does this also happen on the latest trunk version?
http://lib.heron-mc.org/heron/latest/examples/geoportal/index.html

What you are trying (activating all overlays) is also quite heavy. Does this 
also happen with a few overlays?

We prove it with Chrome in MAC and it work Well, but in Chrome Windows 7, 
the problem continues presenting  and this is critical when I use the version 
2.13.1 of Openlayers 

The question is, why  does not Heron use the version 2.13.1 of Openlayers.?

It seems that is an issue from Open layers, you have to disable the CSS 
allowing animations and turning support of GPU on :

OpenLayers-2.13.1/theme/default/style.css

following lines:

/**
 * Animations
 */

      .olLayerGrid .olTileImage {
        /*-webkit-transition: opacity 0.2s linear;*/
        -moz-transition: opacity 0.2s linear;
        -o-transition: opacity 0.2s linear;
        /*transition: opacity 0.2s linear;*/
    }

    /* Turn on GPU support where available */
    .olTileImage {
        /*-webkit-transform: translateZ(0);*/
        -moz-transform: translateZ(0);
        -o-transform: translateZ(0);
        -ms-transform: translateZ(0);
        /*transform: translateZ(0);*/
        /*-webkit-backface-visibility: hidden;*/
        -moz-backface-visibility: hidden;
        -ms-backface-visibility: hidden;
        backface-visibility: hidden;
        -webkit-perspective: 1000;
        -moz-perspective: 1000;
        -ms-perspective: 1000;
        perspective: 1000;
    }
