A few weeks ago, Google became aware of a security issue with WebGL: shaders could be used to indirectly deduce the contents of textures uploaded to the GPU. As a result, Chrome 13 (and Firefox 5) will no longer allow cross-domain media as a WebGL texture. The default behavior will be a DOM_SECURITY_ERR. However, applications may still utilize images and videos from another domain with the cooperation of the server hosting the media, otherwise known as CORS.
