After TextureAtlas is loaded, it's low fps rate for a while

After TextureAtlas is loaded, it's low fps rate for a while

stackoverflowers and other good people, I have one issue with which I
don't know how to solve after a two days of trying: I have libgdx project
(I'm using stages and actors, but that's not important now) where I add to
comments everything not useful and problem is simple:
setting the empty screen first a few (4-5) renderings have delta around
0.04 sec, then around 0,01
setting the screen, where in the resize method I made a new instance of
TextureAtlas - it loads two 1024 x 1024 textures takes around 0.5-0.8 sec
and after that it starts rendering and first few renderings (5) have delta
times around 0.1 sec (on SGS II) or around 0.2 - 0.3 sec (on SG ACE) - and
that's a really quite a problem, because when you have some FadeIn effect
or whatever animation at the start of the screen you will see maybe the
second half of the animation - yea when it has that low fps
rating...nothing is drawing (I can't see anything even it says that
renderings have been called even after 0.3 sec)
My question is: TextureAtlas is supposed to load every page image when
it's called so why it affects running after it has been load? Or at least
whether can I know when it will be running, drawing normally?
Really thanks for your answer!
Obivously here's code, but it's simple as this:
public class App extends Game {
@Override
public void create() {
Gdx.app.log( this.LOG, "Creating game" );
fpsLogger = new FPSLogger();
setScreen( new IntroScreen(this) );
}
}
IntroScreen:
public class IntroScreen implements Screen {
@Override
public void resize(
int width,
int height )
{
super.resize( width, height );
Gdx.app.log("IntroScreen", "Resize start: " );
atlas = new TextureAtlas( Gdx.files.internal(
"image-atlases/pages-info.atlas" ) );
Gdx.app.log("IntroScreen", "Resize finished: " );
}
@Override
public void render(
float delta )
{
Gdx.gl.glClearColor( 0f, 0f, 0f, 1f );
Gdx.gl.glClear( GL20.GL_COLOR_BUFFER_BIT );
Gdx.app.log( "IntroScreen", "Delta: " + delta );
// stage is empty
stage.act( delta );
stage.draw();
}
}
And here is output from LogCat:

Thanks for any help.
