Everything that is supposed to be white is grey. Help! C13

It’s hard to explain, I uploaded a photo to show. Bought and installed C13 and for some reason everything that is supposed to be color white, is grey. The first top line (“Cubase Pro Project - Untitled1”) is the color everything else should be.

Does anyone know what can I do to fix it?

Hi,

What exactly would you expect to be white? Do you mean the menu bar?
