Ok what you are seeing here is we disabled the white out conditions that X-Plane 10 puts forward in these kinds of situations. Its a trade off right now, the white out conditions or as I like to call it "The Grey Screen of Death" isnt a good representation, it actually causes people to crash when hand flying sometimes...... With this being called a trade off, I did notice the transitions myself. It may not be until an update that we will tackle this, but it is an area Id like to improve on..... For now though personally I think it is a better representation of this kind of condition....
