[[1.9] Drawing string in GUI draws two seperate lines.]

hmm i managed to fix my own problem by instead of using the RenderGameOverlay event use RenderGameOverlay.Text i don't understand why this changed anything but it works... i guess

[[1.9] Drawing string in GUI draws two seperate lines.]

Im making a mod that is supposed to draw text on the screen, I'm doing this by creating a GUI and rendering it on the RenderGameOverlay event like this

@SubscribeEvent
    public void onRenderGui(RenderGameOverlayEvent event) {
	new ModList(Minecraft.getMinecraft());
}

and

public class ModList extends Gui{

public ModList(Minecraft mc) {
	drawString(mc.fontRendererObj, "Test", 10, 10, 16755200);
}
}

The problem I am having at the moment is that when I draw the string for some reason it draws the text twice like in this image

Does anyone know why this is occurring?
