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

import net.minecraft.client.Minecraft;
import net.minecraft.client.gui.Gui;
import net.minecraft.util.math.MathHelper;
import net.minecraft.util.text.TextFormatting;
import net.minecraft.world.EnumSkyBlock;
import net.minecraftforge.fml.common.FMLCommonHandler;
import net.minecraftforge.fml.relauncher.Side;
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("defaultHeight") && Reference.isInteger(Reference.setVariables.get("defaultHeight"))) defaultHeight = Integer.parseInt(Reference.setVariables.get("defaultHeight"));
		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) {
    	Minecraft mc = Minecraft.getMinecraft();
    	List<String> output = new ArrayList<String>();
    	Reference.setVariables = new HashMap<String, String>();
    	try {
	    	for (String line : config) {
	    		if (line.startsWith("var ")) {
	    			if (line.split(" ").length == 4) Reference.setVariables.put(line.split(" ")[1], line.split(" ")[3]);
	    		} else {
	    			line = line.replaceAll("\\{playerName\\}", mc.player.getName())
		    		.replaceAll("\\{x\\}", String.format("%f", mc.player.getPositionVector().x))
		    		.replaceAll("\\{y\\}", String.format("%f", mc.player.getPositionVector().y))
		    		.replaceAll("\\{z\\}", String.format("%f", mc.player.getPositionVector().z))
		    		.replaceAll("\\{chunkX\\}", "" + mc.player.chunkCoordX)
		    		.replaceAll("\\{chunkY\\}", "" + mc.player.chunkCoordY)
		    		.replaceAll("\\{chunkZ\\}", "" + mc.player.chunkCoordZ)
		    		.replaceAll("\\{yaw\\}", "" + MathHelper.wrapDegrees(mc.player.rotationYaw))
		    		.replaceAll("\\{pitch\\}", "" + MathHelper.wrapDegrees(mc.player.rotationPitch))
		    		.replaceAll("\\{biome\\}", mc.world.getBiome(mc.player.getPosition()).getBiomeName())

		    		.replaceAll("\\{toggleKey\\}", Reference.getKeyBindingByName("toggleOverlay").getDisplayName())
		    		.replaceAll("\\{configFile\\}", new File("config/MoreCommands/infoOverlay.txt").getAbsolutePath().replaceAll("\\\\", "\\\\\\\\")) // replacing 1 backslash with 2 so backslashes actually show
		    		.replaceAll("\\{facing\\}", Reference.getLookDirectionFromLookVec(mc.player.getLookVec()))
		    		.replaceAll("\\{time\\}", Reference.parseTime(FMLCommonHandler.instance().getMinecraftServerInstance().getWorld(mc.player.dimension).getWorldTime() % 24000L, false))
		    		.replaceAll("\\{UUID\\}", mc.player.getUniqueID().toString())
		    		.replaceAll("\\{holding\\}", Reference.getLocalizedName(mc.player.getHeldItemMainhand().getItem()))
		    		.replaceAll("\\{rainbow\\}", "" + getRandomColor())
		    		.replaceAll("\\{easterEgg\\}", ":O, you found the easter egg!")
		    		.replaceAll("\\{xp\\}", "" + mc.player.experienceTotal)
		    		.replaceAll("\\{xpLevel\\}", "" + mc.player.experienceLevel)
		    		.replaceAll("\\{gamemode\\}", FMLCommonHandler.instance().getMinecraftServerInstance().getPlayerList().getPlayerByUsername(mc.player.getName()).interactionManager.getGameType().getName())
		    		.replaceAll("\\{fps\\}", "" + mc.getDebugFPS())
		    		.replaceAll("\\{blockLight\\}", "" + mc.world.getChunkFromBlockCoords(mc.player.getPosition()).getLightFor(EnumSkyBlock.BLOCK, mc.player.getPosition()))
		    		.replaceAll("\\{skyLight\\}", "" + mc.world.getChunkFromBlockCoords(mc.player.getPosition()).getLightFor(EnumSkyBlock.SKY, mc.player.getPosition()))
	    			.replaceAll("\\{lookingAtX\\}", "" + mc.objectMouseOver.getBlockPos().getX())
	    			.replaceAll("\\{lookingAtY\\}", "" + mc.objectMouseOver.getBlockPos().getY())
	    			.replaceAll("\\{lookingAtZ\\}", "" + mc.objectMouseOver.getBlockPos().getZ())
	    			.replaceAll("\\{lookingAt\\}", "" + Reference.getLocalizedName(mc.world.getBlockState(mc.objectMouseOver.getBlockPos()).getBlock()))
	    			.replaceAll("\\{isSingleplayer\\}", "" + FMLCommonHandler.instance().getMinecraftServerInstance().isSinglePlayer());
		    		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();
}
