See downstream fedora 21 bug, https://bugzilla.redhat.com/show_bug.cgi?id=1103496#c60 "After talking to Benjamin some more, the copy of the old Adwaita css spinner that is in oxygen-gtk now doesn't work anymore because it relied on a background rendering hack that is no longer working. " The suggested (much simpler) css code seems to work as advertised (though it's not using an oxygen style spinner anymore): @keyframes spin { to { -gtk-icon-transform: rotate(1turn);} } .spinner { background: none; -gtk-icon-source: -gtk-icontheme("process-working-symbolic"); } .spinner:active { background: none; animation: spin 1s linear infinite; } Reproducible: Always
