Transparent 2px gap between panel and maximized windows

[JirkaVebr]

Hi,

Since about a month ago after an update I’ve had a 2px gap between my panel and maximized windows, through which I can see my wallpaper. This is what it looks like:

When I first experienced it, I was super busy, and so I shamefully didn’t note what was it that updated that caused this issue. When I hover over an opened window on the panel, it expands to fill the space above it like this:

My Antergos is up to date, and when I switch from Numix-Frost to Numix-Cinnamon or Cinnamon, the issue goes away. Furthermore, a friend of mine is facing the same problem, and so I believe it's a bug of this theme.
