BrowserRenderSettings.startupBehaviour property

How to handle input frames arriving before the CEF browser is ready (i.e. before the first successful paint). CEF takes a moment to load the page and produce its first frame. - "bufferUntilReady" (default): Queue input frames without bound until the browser is ready. Once ready, maxQueueDepth is enforced. Good for file inputs where every frame must be preserved. - "passthroughUntilReady": Emit input frames on the original pin immediately with no corresponding browser frame. Good for live inputs where startup latency matters more than having a browser overlay for the first fraction of a second.
