Decal not showing in Render Viewport in Rhino 6

Hi all. I am having issues with seeing decals in Render View within viewports. it does work well when rendering outside viewport. I mean, in final render, but this time comsuming.
I used Rhino 5 for a long time and never had any issues, but now I am really upset with this issue. Important: I am using the same notebook as before, so it must be something within Rhino 6. Maybe some extra configuration that should be done or maybe it does requires a different graphics card to work, and if this is the case, I will go back to Rhino 5 till I upgrade hardware.
Thanks in advance.
