Shadows are referenced in this string. I hadn't been paying attention to shadows at all. Had a nasty time with the Carenado Malibu on start-up: The panel was so dark, I was having to go to 3-D View, which allows scrolling down, to find lighting knobs. If I wanted to do without 3D, such as quickly loading and shooting a 3 mile or 10 mile approach to a new airport, I couldn't see VS or much of anything. Stumbled upon and completely turned off shadows in Rendering, and that problem is solved. Another, actually more annoying problem has been course changes - now you see the panel and whatever you're looking for inside the aircraft (e.g., landing lights, the ability to double-check whether flaps are extended, etc.), now you don't. As shadows are thrown over the cockpit, you're suddenly IMC in the cockpit!! Mentioning in the event anyone experiences problems with dark panels, sudden dark silhouettes in cockpit - probably due shadows being enabled.
