Gameobjects position change with resolution

Question

I have a scene with multiple GameObjects with x-y-z position. I'm in 2D so the z is not used.

For now, I worked with the resolution 1024/768 and when I add a GameObject like :

GameObject star = GameObject.CreatePrimitive(PrimitiveType.Sphere);
Vector3 position = new Vector3 (x, y, z);
star.transform.localPosition = position;

It's ok, the GameObject is in the right position on my scene.

But nox, I'm trying to change the resolution (1920/1080) and all my GameObjects are moved far on the top right, out of my camera.

What's the problem ? How can I fix this ?

For me, when I change the resolution, the 0-0-0 change for my GameObjects....and something weird, If my GameObject has a LineRenderer with positions, they are good on all resolutions...

Edit : This is the function I use for generate my GameObjects, it's a galaxy generator :

             for(int i = 0; i < numberOfStars; i++) {
                bool checkPosition = false;

                while (!checkPosition) {
                    // Choose a distance from the center of the galaxy.
                    float distance = Random.Range(5.0f, (float) galaxySize / 2 - 5);

                    // Choose an angle between 0 and 2 * PI.
                    float angle = Random.Range(0.0f, 100.0f) * 2 * Mathf.PI;

                    Vector3 position = new Vector3 (Mathf.Cos (angle) * distance, Mathf.Sin(angle) * distance, 9);

                    if (! Physics.CheckSphere(position, 1)) {
                        GameObject star = GameObject.CreatePrimitive(PrimitiveType.Sphere);
                        star.AddComponent<SolarSystem>();

                        star.name = i + "_" + PlanetNameGenerator.GenerateName();
                        star.GetComponent<SolarSystem>().name = i + "_" + PlanetNameGenerator.GenerateName();

                        star.transform.parent = GameObject.Find ("Targets").transform;

                        // On change le scale en random
                        float randomScale = Random.Range (0f, 0.5f);
                        star.transform.localScale += new Vector3(randomScale,randomScale,randomScale);

                        star.transform.localPosition = position;
                        star.tag = "SolarSystem";

                        checkPosition = true;
                    }
                }
            }

This is the scene I see in 1024/768, with my Sphere GameObjects and in pink LineRenderer between them :

This is what I see in 1920/1080, LineRenderer are always in the same position, but GameObjects move away :

Can you provide more code? also provide whether you are using a perspective or orthographic camera, and how are you changing the resolution? — AresCaelum
More code like what ? I'm using a perspective camera, and I change the resolution in the editor, in the game view — Clément Andraud
Show all the code up the point where this is called and the entire function this is in. With what you provided I wouldn't be able to reproduce your error. — AresCaelum
I edited with my function for generate all GameObjects, do you want more ? If yes, like what ? :) — Clément Andraud

The problem was this line :

star.transform.parent = GameObject.Find ("Targets").transform;

I moved the parent out from Canvas, chnage x-y-z positions of "Targets" to 0 et it's ok.
