<div>
<pre>Currently there is no guarantee that pages are actually rendered at the time that LOAD_FINISHED is emitted, and there is no signal to indicate that a page has been rendered, so there is never any safe time to use webkit_web_view_get_snapshot(). In Epiphany we use a hardcoded timeout (0.2 or 0.5 seconds or so) to decide when to call the snapshot API as a workaround for this. Otherwise there is a chance that the returned snapshot would just be a white background.
Preferably LOAD_FINISHED would not be emitted until the page has actually been rendered. Alternatively, we could add a new signal to indicate when it is safe to take a snapshot.</pre>
