Hi there, I'm not entirely sure why this is happening.
I can only guess that it could be anything from an operating system to the graphics card you are currently running.
I know for sure that the graphics card must have the following specs for it to run.
Graphics: OpenGL ES 2.0 hardware driver support is required for WebGL acceleration. (AMD Catalyst 10.9, nVidia 358.50), iOS 8.0, Android 4.4.4*
