RenderTexture 添加子节点坐标的bug

Studio
#1 
m_render = RenderTexture::create(normalSprite->getBoundingBox().size.width /2, normalSprite->getBoundingBox().size.height / 2, Texture2D::PixelFormat::RGBA4444, GL_DEPTH24_STENCIL8);
m_render->setPosition(Vec2(normalSprite->getBoundingBox().size.width / 2, normalSprite->getBoundingBox().size.height / 2));
m_render->clear(0, 0, 0, 0.7f);
m_render->setAutoDraw(true);
addChild(m_render);

this->centerOnPoint(CCPoint(normalSprite->getBoundingBox().getMidX(), normalSprite->getBoundingBox().getMidY()), 1);

auto vmap = DataCenter::GetInstance()->GetValueMap("yhcinfo");
mapLayer::initNodeWithConfig(vmap);

auto paddleTexture = Director::getInstance()->getTextureCache()->addImage("logo.png");
auto aaaa = CCSprite::createWithTexture(paddleTexture);
aaaa->setPosition(Vec2(-100, -100));

m_render->addChild(aaaa);

打开m_render->setAutoDraw(true);自动刷新子节点；
aaaa 的坐标处于比较混乱的状态，移动一个1.0f距离，
相当于父节点的2倍，0，0原点位置在上边界的中心位置

aaaa 的坐标处于比较混乱的状态，移动一个1.0f距离，
相当于父节点的2倍，0，0原点位置在上边界的中心位置

aaaa 比setPosition(-100, -100) 多移动了一个 1.0f的距离？

#3

不是的。
这个父节点是一个可移动的节点，
父节点移动0.5个距离aaaa 会移动大概1.0f的距离
正常的子节点应该是和父节点一样的移动。

你使用的是cocos2d-x的哪个版本？

#5

是3.10官网的版本，大概两个星期前下载的

全部测试代码贴出来，
想不出来这个奇葩的增量是哪来的
