Not really. It's primarily there to refresh OSD during pause or with a slow 
frame rate.

If the vout display plugin is not composited, it can (and should) hold the 
last picture and redraw it upon a damage event or a change of picture 
placement. There are no needs for the core to know about that. In fact, to 
handle partial damage in optimised fashion, you really don't want the core to 
be involved.

Refreshing the display in the core is just legacy bug compatibility.
