Describe the bug

1. Open ScrCpy using these flags:

C:\android\scrcpy\scrcpy-noconsole.vbs -S --always-on-top --stay-awake --no-audio

2. Run some app that will change the orientation every now and then, or use adb to do it somehow in the background using a script that does the same.

Here's a sample app to simulate this, which changes the orientation after 5 seconds since shown.

My Application.zip
app-debug.zip

Code:

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        Handler(mainLooper).postDelayed({
            requestedOrientation = if (resources.configuration.orientation == ActivityInfo.SCREEN_ORIENTATION_PORTRAIT)
                ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
            else
                ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
        },  5000L)
    }
}

3. Open some app on Windows that needs focus, such as a game in full screen or a video player that's in full screen or on top.
4. Wait for the Android app (or script) to change the orientation while you use the app on Windows that should stay in focus.

The bug is that ScrCpy steals the focus because of it, as you can see here:
