After the latest update one of the improvements is ghosting doesnt occur anymore. Earlier ghosting was apparent in many places (after book menu or dictionary lookup shown, or after waking device from sleep). So, kobo has a complete refresh (or full refresh) after each of these activities (in case of sleep-wake and dictionary lookup, refresh happens during next page turn and in case of menu it happens immediately).

As I said earlier (and others have commented before) the ghosting is almost completely absent now and the full refresh (which is an eye sore and a disturbance) is unnecessary now. It will be great if kobo removed/disabled this full refresh (at least as an option).
