[1.10.2] Keeping a DynamicTexture "Alive"

I'm i correct that to keep a Dynamic Texture "Alive" (as in always an allocated OpenGL texture) you need to use a modified texture class which forces the dynamic texture to update when loadTexture is called (Texture Manager seems to call it when onResourceManagerReload is called) ? Is there anywhere where Minecraft could delete the OpenGL texture without calling a loadTexture?

package stucuk.square.client;

import java.io.IOException;

import net.minecraft.client.renderer.texture.DynamicTexture;
import net.minecraft.client.resources.IResourceManager;

public class SquareDynamicTexture extends DynamicTexture {

	public SquareDynamicTexture(int textureWidth, int textureHeight)
	{
		super(textureWidth, textureHeight);
	}
	
	@Override
	public void loadTexture(IResourceManager resourceManager) throws IOException
    {
		updateDynamicTexture();
    }

}
