Hi everyone!
I have a problem. I use cocos2d-x v3.6 and I have this png file 
It’s 9x9 texture with 1 pixel wide blue border. I init Scale9Sprite with it and with cap insets {4, 4, 1, 1}. On some resolutions problem appears - some borders are thiner. For example bottom border is thiner than the right one. Here you can see the difference 
If I create Sprite with this texture everything is fine - can be seen in example. So why does this happen and how it can be fixed?
