And the globe wireframe doesn't show either on my QHD monitor or in my FullHD portrait...

Looks like you fall between a couple of sweet spots with the responsive design. If you reduce your browser width a bit more I'm guessing you see the brighter globe wireframe disappear and the search bar becomes more obvious?

They could probably fix this by throwing in some more media queries that do the same thing (toggle the brighter globe) but based on `min-height` rather than width-alone.
