For some reason (idk why) i have a problem with (sry i dont know how it in english) double or triple(or more) vision screen when i'm trying to install high sierra on a disk using VNC. Already tryed doing this with gpu passed through, same result. But if i try to do it with a VNC + gpu passtrough - on a gpu picture is normal, but i see just a piece of screen. This happened with only a High Sierra.
P.S. sorry for my bad english
