when using a WebView through AndroidView, sometimes the page is not shown. It appears to be random (the same page appears sometime, but sometimes it does not). When the problem happens, sometimes the following error shows up in logcat:

The way I instantiate webview is :
Copy code
fun WebViewView(html: String, ...) {
    AndroidView({ context ->
        val webView = WebView(context)
        // configure webview
This have been happening in all compose versions I have tried. I have not found any similar problem in the bug tracker. Am I doing something wrong? Should I report a bug?
