I have upgraded a Debian 7 system to Debian 8 and, among other changes, when I log in using gnome-classic, the desktop background is new. However, my gnome menus have not changed, as you can see in this screenshot:
So, I have performed a fresh installation of Debian 8, and on that I get the following look and feel when I log in as gnome-classic:
Why are the icons, the menu look and feel, and the upper tool bar different?
Can it be that some packages have not been upgraded properly when going from Debian 7 to Debian 8?
If this is the case, is it possible to restore the look and feel of the upper picture in Debian 8?
