I have two problems with GNOME Classic under Fedora 21.
The first one is that I get automatically a GNOME Files window opened when I log in:
Then, it looks like Qt applications have not appearance modifications. Look how Qt Creator looks different between GNOME Classic:
And under standard GNOME:
As you can see, the fonts and icons are totally different. Also, the Qt Creator file opener looks like the Qt file opener while on GNOME it uses the Gtk one.
I use almost everything by default.
