Also on axmol: Cococ2dx issue: FlipY3D issue if setDesignResolution and RenderTexture is used

[aismann]

Steps to Reproduce:
see cocos2d/cocos2d-x#20767
=> has the full source also

here the important source snippet (see on draw()):

#include "HelloWorldScene.h"

USING_NS_AX;

Scene* HelloWorld::createScene()
{
    return HelloWorld::create();
}

// on "init" you need to initialize your instance
bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
    if (!Scene::init())
    {
        return false;
    }

    auto visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();

    mSpritesLayer = Layer::create();
    mSpritesLayer->retain();

    sprite = Sprite::create("mario_3x.png");
    sprite->getTexture()->setAliasTexParameters();
    sprite->setAnchorPoint(Vec2(0, 1));
    sprite->setScale(visibleSize.height / mDesignSize.height);
    sprite->setPositionY(visibleSize.height);
    sprite->setPositionX(0);
    mSpritesLayer->addChild(sprite);


    // RenderTexture
    mRTex = RenderTexture::create(visibleSize.width, visibleSize.height);
    mRTex->setPosition(visibleSize.width / 2, visibleSize.height / 2);
    this->addChild(mRTex, 100);


    mNodeGrid = NodeGrid::create(Rect(origin,visibleSize));
    mNodeGrid->retain();
    mNodeGrid->setTarget(mSpritesLayer);
    
    mFlipY3dAction = FlipY3D::create(1);
    mFlipY3dAction->retain();

    return true;
}

void HelloWorld::draw(ax::Renderer* renderer, const ax::Mat4& transform, uint32_t flags)
{
    if (mTick == 50)
    {
        mNodeGrid->runAction(mFlipY3dAction);
        mNodeGrid->resume();
    }
    mTick++;
    Scene::draw(renderer, transform, flags);

    // The code below works fine when RenderTexture is not used
  //  mRTex->beginWithClear(0, 0, 0, 0); // comment out and it works
    
    mNodeGrid->visit(renderer, transform, flags); // maybe transform issue?

   // mRTex->end(); // comment out and it works
}

Removed it. Its also on the cocos forum.
