I have made an overlay gui with some information of the player but when you hover over an entity it dissapears.

InfoOverlay.class:

package com.ptsmods.morecommands.miscellaneous;

import java.io.IOException;
import java.util.ArrayList;
import java.util.HashMap;

import net.minecraftforge.fml.relauncher.SideOnly;

@SideOnly(Side.CLIENT)
public class InfoOverlay extends Gui {

	private Minecraft mc;
	
	public InfoOverlay() {
		this.mc = Minecraft.getMinecraft();
		this.zLevel = Float.MAX_VALUE;
		try {
			Reference.loadInfoOverlayConfig();
		} catch (IOException e) {
			e.printStackTrace();
		}
		drawStrings(parseInfoOverlayConfig(Reference.getInfoOverlayConfig()).toArray(new String[0]));
	}
	
	private void drawString(String string, int row) {
		int defaultHeight = 2;
		int defaultWidth = 2;

		if (Reference.setVariables.containsKey("defaultWidth") && Reference.isInteger(Reference.setVariables.get("defaultWidth"))) defaultWidth = Integer.parseInt(Reference.setVariables.get("defaultWidth"));
		drawString(this.mc.fontRenderer, string, defaultWidth, row*10 + defaultHeight, Integer.parseInt("FFFFFF", 16));
	}
	
	private void drawStrings(String... strings) {
		for (int x = 0; x < strings.length; x++) {
			drawString(strings[x], x);
		}
	}
	
	private TextFormatting getRandomColor() {
		if (Reference.Random.randInt(101) == 0) {
			Reference.lastColor = Reference.getRandomColor("WHITE");

		return Reference.lastColor;
	}
	
    private List<String> parseInfoOverlayConfig(List<String> config) {

		    		if (line.equals("") || !line.split("//")[0].equals("")) output.add(line.split("//")[0]);
	    		}
	    	}
    	} catch (NullPointerException e) {}
    	return output;
    }
}

How I render it (in ClientEventHandler.class):

@SubscribeEvent
public void onRenderGui(RenderGameOverlayEvent.Post event) {
	if (event.getType() == ElementType.EXPERIENCE && Reference.isInfoOverlayEnabled()) new InfoOverlay();
}
