Window decorations and my theme

Weird thing started a few days ago. Its in my Ubuntu MATE 24.10 Virtual Machine. I use the same theme in VM as I do in my daily driver. It's called Mojave-Dark-solid, and is modelled closely from macOS. The first screenshot shows the window controls as expected by the theme (Gnome-look.org). The second screenshot is from Chromium (The only application that produces the window decorations that do not match the other applications. Not 100% MATE related, but I would appreciate some insight. Being OCD, this issue practically keeps me awake all night. I have tried different themes, (Chromium, not WM themes), and no theme and when I switch back to Mojave-Dark-solid, it goes back to the wrong colours in the Chromium browser.
