[1.13.2] What is this?

Guys, when I call some method (GuiNewChat) to call previous chat history in custom chat method.
Here's the result .. 

public void onRenderGui(RenderGameOverlayEvent.Post event)
 {if (Minecraft.getInstance().currentScreen instanceof NewChat)



{
Minecraft.getInstance().ingameGUI.getChatGUI().drawChat(1);

}

}

How can I fix its location?

I tried to add some glstatemanager class from referring some previous classes like forgeingamegui.class

in that class... there the codes look like..

    protected void renderChat(int width, int height)
    {
        mc.profiler.startSection("chat");

        RenderGameOverlayEvent.Chat event = new RenderGameOverlayEvent.Chat(eventParent, 0, height - 48);
        if (MinecraftForge.EVENT_BUS.post(event)) return;

        GlStateManager.pushMatrix();
        GlStateManager.translatef((float) event.getPosX(), (float) event.getPosY(), 0.0F);
        persistantChatGUI.drawChat(ticks);
        GlStateManager.popMatrix();

        post(CHAT);

        mc.profiler.endSection();
    }
