FrameBufferSample has problem on resize

[Juankz]

When the transition is going the framebuffer render the image with black bars. Any idea how to solve it?

This is the picture. The screen has been resized.

This is when transitioning

The problem is, that drawing to the framebuffer is done with the wrong viewport sizes. You can fix it by adding a viewport.update() before drawing to the framebuffer:

private void updateStatePicture() {
    ...

    if (time > GALLERY_PICTURE_TIME) {
        viewport.update(VIRTUAL_WIDTH, VIRTUAL_HEIGHT);
