Hello Guys!!! I was designing my UI when I came with this problem:
I Created an Image, then I put inside the Sprite and set it to Native Size, but as you can see, not all the pixels are grouping together as they should, this is the config I´m using for my camera and Canvas:

Thanks to everyone!!!, hope someone can help me.

How does it look when you set your Game window Scale to 1 rather than 3.23? If it looks okay, then perhaps it is just because you are sizing the contents of the Game window by a decimal amount.
It looks exactly the same
I´ve been trying things and I cannot find where is my error, this is the sprite and canvas Settings im using now:
Have you tried it in a build? One of the issues with the game view is it is almost always scaled even with the slider set to 1. I believe it’s rendering to a render texture and with the resize algorithm it can cause that to happen.
A few hints:
- Never trust the editor and the build to be the same.
- Always test it in a build to see how it looks and functions.
- Pixel graphics are a pain the behind to get right.
Yes, the problem persists when running the game (you can see that the pixels on the right side are not the same size):

I think that my pixels are not matching the pixel size on the inspector, but how can I change them?? I have set the pixels per unit in the sprite,and set the same pixels per unit in the canvas, and then set the image size to Native size, how is this possible?
