Android 5.0 popup window cropping not working

Question

I have a popup that represents a circle, and I want it to be partially off-screen. To call the window, I used: popup.showAsDropDown(imageButton, OFFSET_X, OFFSET_Y);And it should look like this:

To copy the view I used: popup.setClippingEnabled(false); And it works, it looks as I expect on devices with an API level below 21 ...

Unfortunately, on android L (candy), it looks like this:

The circle is cropped on top, but on the right side it just fits to the edge of the screen. Any ideas how to solve this problem?

I add the source code in which I call the popup

private void showPopup(final Activity context, ImageButton imageButton ) {
    // Inflate the popup_layout.xml
    FrameLayout viewGroup = (FrameLayout) context.findViewById(R.id.popup);
    final LayoutInflater layoutInflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    final View layout = layoutInflater.inflate(R.layout.popup, viewGroup);

    layout.startAnimation(range_animation_start);

    layout.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);

    int popupHeight = layout.getMeasuredHeight();
    int popupWidth = layout.getMeasuredWidth();
    // Creating the PopupWindow
    final PopupWindow popup = new PopupWindow(layout);
    popup.setContentView(layout);
    popup.setWidth(popupWidth);
    popup.setHeight(popupHeight);
    popup.setFocusable(true);


    // Some offset to align the popup a bit to the right, and a bit down, relative to button position.
    int OFFSET_X =getResources().getDimensionPixelOffset(R.dimen.width_offset);
    int OFFSET_Y = getResources().getDimensionPixelOffset(R.dimen.height_offset);

   // Clear the default translucent background
    popup.setBackgroundDrawable(new BitmapDrawable());
    popup.setClippingEnabled(false);

    // Displaying the popup at the specified location, + offsets.

    popup.showAsDropDown(imageButton, OFFSET_X, OFFSET_Y);
