That's a GTK+ spinner widget, which uses RENDER trapezoids, which is a
software rendering fallback with EXA.

I don't think there's anything wrong with the animation per se. However,
one issue I've found is that Evolution schedules many actions as glib
idle callbacks with priority lower than G_PRIORITY_HIGH_IDLE + 20, which
is the priority used by GTK+ for drawing animations. This can result in
the animations delaying the completion of the actual work they're
representing.
