Aircraft preview does not work

[Bakelit]

A small issue I have:

In Aircraft menu, where you can select country and markings, etc the preview on the left does not show up. Sometimes it flickers for a split second and I can sense an aircraft.

Surely something that can be changed on my end ? Maybe NVidia drivers or such? ( certainly it's not a general bug as I have not yet read about it)

Also changes in the menu eg Blue, Germany, etc do not stick. State of the art ?
