See also bug #1177683: Confirmed on a macbook air 6,2. if I disable the 'Background Logo' extension via https://extensions.gnome.org/local/ then the gnome-shell idle cpu usage drops to <1%. I did some more digging, and noticed that I it seems to be an issue with certain logo files only, chosen from /usr/share/pixmaps via the extension's settings panel. E.g. the 'fedora-logo.svg' logos causes approx 50% CPU. The 'fedora-logo.png' PNG format logo has the same issue. However, if I choose 'fedora-logo-sprite.png' or 'fedora-logo-sprite.svg' I do not see the gnome-session idle CPU above 1%.
