Thank you for raising the issue, can you elaborate a little on how you're using the showcase view in your application.

Should I assume you're using a custom image on one of the overlays?

[Elaws]

Thanks for your answer :

I've only used "rounded rectangle" showcase views a single "no focus" showcase view. No custom image has been used on one of the overlays.

Rounded rectangle views :

I use a boolean ("hasTuto") to define whether showcase view should be displayed or not once a button or textView has been touched. Their event handlers are similar and look like this :

public void OnButtonTouch(object sender, View.TouchEventArgs touchEventArgs)
        {
            View view = (View)sender;

            if(hasTuto)
               Tuto(view);
            else 
               // Normal behavior
        }

Tuto function being :

        public void Tuto(View view)
        {
            ShowCaseView showcase = new ShowCaseView.Builder()
                .Context(this)
                .FocusOn(view)
                .FocusShape(Xama.JTPorts.ShowcaseView.Models.FocusShape.RoundedRectangle)
                .CloseOnTouch(true)
                .BackgroundColor(Color.LightBlue)
                .FocusBorderColor(Color.White)
                .Title("tutoName")
                .Build();

            showcase.Show();
        }

No focus view :

This view is used on any listView item click :

 public void OnListViewItemClick(object sender, AdapterView.ItemClickEventArgs args)
        {
            if (hasTuto)
                Tuto();
            else
                // Normal behavior
        }

Tuto function being here :

        public void Tuto()
        {
            ShowCaseView showcase = new ShowCaseView.Builder()
                .Context(this)
                .CloseOnTouch(true)
                .BackgroundColor(Color.LightBlue)
                .FocusBorderColor(Color.White)
                .FocusBorderSize(15)
                .Title("tutoText")
                .FocusCircleRadiusFactor(1.5)
                .Build();

            showcase.Show();
        }

Bear with me, I'll recreate the above in the sample application and get back to you as soon as I am able.
