That's a pitty. I just upgraded to LE 8.x from LE 7.02 .. well it worked there on an NVIDIA and NUC system .. . and found that my beloved hyperspace screenblanker (typically running on a 110" screen as a pre-movie warm-up) does not work anymore 
Btw, thanks for the hints here. Prevented me from wasting time checking my faults and installation.
I suspect there are higher priorities - is there any chance that these will be fixed with LE 9 / Lei?
