LibGDX: Content appears stretched although I'm using a ScreenViewport

Question

I just fixed another issue regarding the scaling inside a ScreenViewport. And yet another problem arises:

If I'm understanding the wiki correctly, a ScreenViewport does not scale or stretch the content in any way. In my case it somehow does:

When the game is started, it looks like this:

And after resizing the window (e.g. making it wider) it looks like this (obviously stretched...):

(The code is mostly still the same as in the linked question).

Since I couldn't find a example of using a ScreenViewport with unitScale yet, I have no idea how to make this work... Thanks in advance :)

You should call viewport.update(width, height); inside resize method of screen.

@Override
public void resize(int width, int height) {
    viewport.update(width, height);
}

\$\begingroup\$ I did that, but the resize(width, height) call wasn't forwarded properly to the screen. That's solved now, but now the viewport is only displayed correctly when resizing (it's flickering between the right viewport scale and the stretched behavior...). \$\endgroup\$

\$\begingroup\$ Ok, I figured out that it's caused by rendering the RayHandler... \$\endgroup\$

So, to make it work I needed to call useCustomViewport(x, y, width, height) on the rayHandler inside of resize(width, height).

\$\begingroup\$ I downvoted this because Andrej posted the answer two hours before you answered your own. He could not have known you where calling your viewport useCustomViewport without seeing your code. Accept his and delete this one to get rep back. \$\endgroup\$

\$\begingroup\$ @MennoGouw Also, the useCustomViewport was causing this strange display behavior, since I didn't call it in resize and my constructor. \$\endgroup\$

\$\begingroup\$ I overlooked that. But still the answer of Andrej is proper. \$\endgroup\$

\$\begingroup\$ @MennoGouw It's totally valid, but I did call viewport.update(width, height), so that wasn't the cause, which means that his suggestion wasn't the solution. \$\endgroup\$
