Use 'this.add.renderTexture' and then 'game.destroy(true)' error.

Your example works fine for me, as long as I don't use setTimeout to destroy the game - which you should never do, as it's outside the game flow.

Here's a test I created: http://labs.phaser.io/view.html?src=src%5Cgame%20objects%5Crender%20texture%5Cdestroy%20game%20with%20render%20texture.js&v=dev

Thank you. Hopefully there will be more information about using Phaser to create games with aspects like this that require special processing for development. Thank you.（谢谢您。希望有多一些关于使用Phaser创建游戏 像这种需要特殊处理方面的介绍便于开发，谢谢。）

Sorry for duplicated issue (#4876).
In Rich's testing, it saves texture of rendertexture to 'bubbleboy', in line 32. If change the testing to this :

var config = {
    type: Phaser.AUTO,
    parent: 'phaser-example',
    width: 800,
    height: 600,
    backgroundColor: '#2d2d88',
    scene: {
        preload: preload,
        create: create
    }
};

var game = new Phaser.Game(config);

var rt;
var bubbles = [];

function preload ()
{
    this.load.image('dude', 'assets/sprites/phaser-dude.png');
}

function create ()
{
    rt = this.add.renderTexture(0, 0, 80, 80);

    var circle = this.add.circle(0, 0, 40, 0x6666ff).setAlpha(0.5).setVisible(false);

    rt.draw(circle, 40, 40);
    rt.draw('dude', 24, 20);

    this.input.on('pointerup', function () {

        game.destroy(true);

    });
}

Error message will still show on console.

这样可以解决问题，我觉得Phaser官方应该修复解决这个问题。

Thank you for submitting this issue. We have fixed this and the fix has been pushed to the master branch. It will be part of the next release. If you get time to build and test it for yourself we would appreciate that.
