This happens in 4.8 and 7 as well. Since just recently for whatever reason my view port will not show anything when in perspective view mode. It is just a gray (grey?!) screen. However if I set my view mode to any of the ortho settings my model will render, in all light modes, no problems. If I go back to perspective however just a grey (gray?!) screen. Not sure whats going on seems to only be in blueprint viewport.
I haven’t changed any settings since it last worked and it happens in older versions of my project, as well as 4.9. As far as I’m aware it doesn’t happen on my laptop. Computer is Ati card, Laptop is N’vidia, if it makes any difference.
