Hello, I am currently developing a game streaming application using ReplayKit and Broadcast Upload Extension. I would like to ask for your assistance regarding capturing snapshots of a WKWebView in the upload extension without adding it to a visible view hierarchy. From my understanding, calling takeSnapshot(with:) on a WKWebView that is not added to the view hierarchy generally works for simple web pages. However, when it comes to more complex web content — such as animations or WebGL — the snapshot returns a blank or static image. I believe this is because rendering such content requires access to the GPU, which is not fully available when the web view is off-screen. That said, I’ve observed that certain apps are able to capture live animated web content inside their broadcast upload extensions, even when the main app is terminated. This suggests that the snapshot is not being generated by the main app or from a remote server — especially since the network activity confirms the content is served locally (via localhost or local IP). Given this, I believe there must be a way to achieve GPU-accelerated rendering for WKWebView directly within the upload extension context, without attaching it to the app's UI. I would greatly appreciate any guidance, APIs, or recommended techniques that could help me achieve this behavior correctly and within system limitations. Thank you in advance for your support. I look forward to your advice. Warm regards,

After logging in to the main App, turn on screen recording, then switch to the interface of another App to perform operations. After about ten-odd minutes, when returning to the main App, it was found that the app was forcefully quit by the system, and subsequent operations could not be carried out.
