I'm using the lastest version of Openlayers 3, aka 3.15.1. I want to use

layer = new ol.layer.Image({
    map: olMap,
    source: new ol.source.ImageVector({
        source: new ol.source.Vector(),
        style: layerStyle
    })
});

because i have some layer and a lots a features with hover events, so i wanted to put some layer into an ImageLayer to have better perf.

But when i drag'n'drop my ImageLayer, the part that are out of screen are not rendering when dragging, only when the drop occurs.

Is there something to get a render even when dragging (and animating, interacting, etc...)

i'm ok if i need to modify the openlayers build

You can configure your ol.source.ImageVector with a higher ratio value, e.g. 2 instead of the default of 1.5. This will pre-render a larger image, so you won't reach the edge of the rendered map so early. See http://openlayers.org/en/latest/apidoc/ol.source.ImageVector.html.
