Node width is not same on different Position X coordinate

cocos2d-x

I have a guider line in my game which for some reason doesn’t has the same width when positioned on different X coordinate.

Square.png is a simple white 10px x 10px image that i use to scale to the size of the Sprite’s contentSize.

bool GuiderNode::init() {
   if ( !GameSprite::initWithFile("Misc/Square.png") ) { return false; }
   this->setColor(Color3B::BLUE);
   return true;
}

void GuiderNode::update(float posX, float height) {
   this->setContentSize(Size(1, height));
   this->setPositionY(10.0);
   this->setPositionX(posX);
}

After calling the GuiderNode::update method I’ve printed the X position to console and it has following values: 193.0, 159.0. The width of the GuiderNode is set to 1 point in this case, but it looks different for each X position:

In realtime pixel size (iPhon 5s):
X = 193.0, the width is 3px
X = 159.0, the width is 2px

iPhone x everything looks fine, but other devices, it varies the width.

Does anyone know why width of the node is not same?

Is there any rasterisation configuration should be activated/deactivated? Or maybe the scaling is not correctly done?

not sure but i think it was this line in base/ccConfig.h:
#ifndef CC_NODE_RENDER_SUBPIXEL
#define CC_NODE_RENDER_SUBPIXEL 1
#endif

Thanks @bananni, I have tried with this configuration enabled and disabled, and it behaves equally.
