libgdx - using system cursor

[DopplerFrog]

Hi,

I am trying to use the change the system cursor but for some reason it keeps using the default arrow cursor.
any idea what I am missing?
I tried this in version libgdx 1.9.5 and in version 1.6.5.

public class CursorTest extends ApplicationAdapter {
	SpriteBatch batch;
	Texture img;
	
	@Override
	public void create () {
		batch = new SpriteBatch();
		img = new Texture("badlogic.jpg");
		Gdx.graphics.setSystemCursor(Cursor.SystemCursor.VerticalResize);
	}

	@Override
	public void render () {
		Gdx.gl.glClearColor(1, 0, 0, 1);
		Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
		batch.begin();
		batch.draw(img, 0, 0);
		batch.end();
	}
	
	@Override
	public void dispose () {
		batch.dispose();
		img.dispose();
	}
}

The release notes of version 1.8.0 contain this:

“- API Change: cursor API has been cleaned up. To create a custom cursor, call Graphics#newCursor(), to set the custom cursor call Graphics#setCursor(), to set a system cursor call Graphics#setSystemCursor(). The Cursor#setSystemCursor method has been removed as that was not the
right place. Note that cursors only work on the LWJGL, LWJGL3 and GWT backends. Note that system cursors only fully work on LWJGL3 as the other two backends lack a means to set a specific system cursor. These backends fall back to displaying an arrow cursor when setting any system cursor.”

Maybe It has something to do with the backend. if so, how do I know what backend libgdx is using?
