Tap Target Prompt don't highlight correct in the bottom of the screen

Question

I want to use MaterialTapTargetPrompt for an in-app tutorial.

When I want to highlight a Button from BottmNavView, it don't overlay the bottom side of the screen like is shown in the image from left.

If I open the keyboard (pressing on the + Button), the screen is resizing and the Tap Target cover the bottom side of the screen like is shown in the image from right.

I think is the problem is with screen because if I manually add position of Target, I get same results.

The code is this:

fun showTapTargetPrompt(view: View) {
        val builder = MaterialTapTargetPrompt.Builder(this)
            .setTarget(view)
//          .setTarget(260f, 1800f) 
            .setPrimaryText("Prim text")
            .setSecondaryText("Second Text")
            .setAutoDismiss(false)
            .setPromptBackground(DimmedPromptBackground())
        builder.show()
    }
