I have the latest version of SketchUp and the latest versions of Enscape and Nvidia drivers. When i try ro change Glass material it doesn’t change. It changes only if I change mode to White. In older projects where I used older versions of everything it works like i have to. I think it’s because of color rendering or somewhat.
What settings have you got for the glass material itself? It looks like it has some kind of opacity reduction and is rough.
