You could try to configure layer's buffermode. As an example:
DFBDisplayLayerConfig layerConfig;
layerConfig.flags = DLCONF_NONE;
layerConfig.flags |= DLCONF_BUFFERMODE;
layerConfig.buffermode = DLBM_BACKVIDEO;
ret = layer->SetConfiguration(layer,&layerConfig);
if (ret != DFB_OK)
{
DirectFBError ("gdk_display_open: SetConfiguration", ret);
directfb->Release (directfb);
directfb = NULL;
return NULL;
}
And remember that you need to flip manually.
