My game runs full-screen portrait mode and is based on NativeActivity. The Kotlin layer has the following function for setting immersive mode in onCreate, as per the instructions here:

https://developer.android.com/develop/ui/views/layout/immersive

    private fun setImmersiveMode() {
        window.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
 
        // https://developer.android.com/develop/ui/views/layout/immersive
        val windowInsetsController = WindowCompat.getInsetsController(window, window.decorView)
        windowInsetsController.systemBarsBehavior = WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE

        // THIS LINE CAUSES THE PROBLEM
        windowInsetsController.hide(WindowInsetsCompat.Type.systemBars())
    }

This works as expected where the navigation bar at the bottom disappears but the user can swipe up to use it. However it causes an issue with floating widgets because they can't be dragged all the way to the bottom of the screen where the (X) is located.

I've attached two screenshots. Screen1.png shows how closing a floating widget should work where you can drag it all the way down to the (X). In order for this to work I must comment out the last line above which hides the System Bars.

When I do hide the System Bars with the last line above, the floating widget will only drag to just above the (X) and thus it can't be removed from the screen. This is shown in Screenshot2.png

I've seen this behavior on the Samsung S23 as well as the Pixel Pro 8, both running Android 14. Based on the ability to cause this behavior by simply adding the line above, it seems like an OS bug.
