*
* It's a workaround because the only way found to avoid the "artifacts" problem
* is to download from GPU the RenderTexture data and then utilize a temporary
* Texture to upload data and draw them properly.
* During this data migration, data need to be flipped, otherwise will be shown upside down
*
* In order to avoid to create multiple temporary texture during each Draw pass,
* we make sure to create just one.
