Hey everyone !
The brand new iOS 10 update fracking sucks to load BJS cube textures.
I've already had noticed this problem several month ago (on iOS 9) but it happened only very occasionnaly (and pretty randomly). But now, since iOS 10, I don't know what Apple has changed but the bug is happening at least 9 times out of 10, in every mobile browser on iOS.
What the bug is exactly ? When a cube texture is loaded, the cascadeLoad call in Engine.createCubeTexture bugs in the callback
