Black line between cube faces with Lumia

I recently tested this link with http://d8d913s460fub.cloudfront.net/krpanocloud/we…x.html?v=119pr3 (in first page of the Pre Realase 3 discussion) with Nokia Lunia 1020 with Windows Phone 8.1, but you noticed black lines between the faces of the cube ... ???

Please, see the attached images.
I tried to change all the settings to set but the result does not change.
What do you think about this strange behavior on Lumia.

Thanks in advanced, Marco

Hi Klauss, in these days I did many tests.
I thought that the problem was the phone (device, system, or browser side driver ...), but then I tested a new example with 1,020 Lumia with Windows Phone 8.1 that works very very fine... !!! with the same smartphone.

Here the example: http://www.marcostucchi.com/temp/d/viewer/….xml&html5=only
Thanks to Matteo Visintanier for this example.

This new example works very fine and your example unfortunately (http://d8d913s460fub.cloudfront.net/krpanocloud/we…x.html?v=119pr3 - in first page of the Pre Realase 3 discussion) is not working fine. There are the always the black lines.
Why this strange behavior ... ??? I would like to understand the cause!!!
How can I help you to understand and fix it.
It could be a small bug in the player ... ???
If you want the project send me a MP.

Thanks, Marco

Hi Klauss,
