When in fullscreen, the buttons to minimize and close don't appear when hovering the mouse

[Leonardo Müller]

When in fullscreen, the buttons that should appear when hovering the mouse cursor centered on the top of the display don't appear. They still have the function but, as it's impossible to see them, it's not possible to see if the button will close or minimize the session.

I'm using vinagre with the VNC protocol to see and use my desktop, which is in the local network.

I had this bug with virt-manager in Artful. It's curious to see it back, but now in vinagre.
