To curb the issue i set a delay like this and seemed like a better solution than what was left by DuckDuckGo on their browser:

 override fun onResume() {
        super.onResume()

        loadingBar.visibility = View.VISIBLE
        loadingLogo.visibility = View.VISIBLE

        loadingContainer.visibility = View.VISIBLE
        webView.visibility = View.INVISIBLE

        // You can also start a fade-in or animation if desired

        // Optional delay (1 second) before hiding logo and showing WebView
        Handler(Looper.getMainLooper()).postDelayed({
            loadingContainer.visibility = View.GONE
            loadingBar.visibility = View.INVISIBLE
            loadingLogo.visibility = View.INVISIBLE
            webView.visibility = View.VISIBLE
        }, 1000)

        webView.onResume()

        Log.d("MainActivity", "onResume: Showing loading logo")
    }

it shows forcedly the image of the logo itself and waits 1000ms to make webview visible, instead of flickering it's an option, BUT couldn't find the solution they did: chrome and brave. Chrome and Brave basicly doesn't make the app pause or die as minimized, and i don't know if it's a work on chromium engine itself or what
