Hello! I took some advice from a previous post about 4k scaling issues in SW2018. It seems to have worked, but I now have this weird visual glitch in the viewfinder. When I click inside it, it is like the whole SW window is projected inside the viewfinder window, and zoomed in. Very strange. But it goes away when I pan or rotate for example. Has anybody come across anything like it?  

Kind Regards, student Asger from Denmark.
