libgdx borderless fullscreen

Question

I try to give the user the option of how he wants to play the game. Window and Fullscreen Mode is no problem. The thing I don't seem to get to work is the borderless fullscreen/windowed fullscreen. I searched the web and found only one site that helped me:

I did as I was told and I think it kinda works, my problem is, the windows 10 toolbar at the bottom is always in front of the window. Here the picture of how it looks:

The color is awful, but just for testing purposes. Code looks like this:

if (screenManager.FULLSCREEN) {
    Gdx.graphics.setDisplayMode(Gdx.graphics.getDesktopDisplayMode().width, Gdx.graphics.getDesktopDisplayMode().height, true);
} else if (screenManager.WINDOWEDFULLSCREEN) {
    System.setProperty("org.lwjgl.opengl.Window.undecorated", "true");
    Gdx.graphics.setDisplayMode(Gdx.graphics.getDesktopDisplayMode().width,
    Gdx.graphics.getDesktopDisplayMode().height, false);
} else {
    Gdx.graphics.setDisplayMode(screenManager.WIDTH, screenManager.HEIGTH, false);
} 

How can I fix this?

Edit: I updated to 1.9.2, which doesn't has the setDisplayMode method. The code now looks like this:

DisplayMode mode = Gdx.graphics.getDisplayMode();
if (screenManager.FULLSCREEN) {
    Gdx.graphics.setWindowedMode(Gdx.graphics.getDisplayMode().width, Gdx.graphics.getDisplayMode().height);
    Gdx.graphics.setFullscreenMode(mode);
} else if (screenManager.WINDOWEDFULLSCREEN) {
    System.setProperty("org.lwjgl.opengl.Window.undecorated", "true");
    Gdx.graphics.setWindowedMode(Gdx.graphics.getDisplayMode().width, Gdx.graphics.getDisplayMode().height);
    //Gdx.graphics.setFullscreenMode(mode);
} else {
    Gdx.graphics.setWindowedMode(screenManager.WIDTH, screenManager.HEIGTH);
}

Everything works like before, just the borderless fullscreen has the windows toolbar(the thing on the botton) infront of it, just like in the picture. Normal fullscreen works fine.

Answer 1

Just tested the following config on my machine with Windows 10 and it worked:

public class DesktopLauncher {
    public static void main (String[] arg) {
        LwjglApplicationConfiguration config = new LwjglApplicationConfiguration();
        config.width = LwjglApplicationConfiguration.getDesktopDisplayMode().width;
        config.height = LwjglApplicationConfiguration.getDesktopDisplayMode().height;
        config.fullscreen = true;
        new LwjglApplication(new MyGame(), config);
    }
}

You should set that in DesktopLauncher in desktop module

UPDATE
You should try:

Gdx.graphics.setFullscreenMode(Gdx.graphics.getDisplayMode());

Also, what version of LibGDX are you using? I'm on version 1.8.0 and I don't have Gdx.graphics.setDisplayMode() method.
