[Kinda Solved] Screen.width + ExecuteInEditMode + OnEnable returns width of an inspector window

It's basically the same old question, but I couldn't find a way to workaround this yet.
https://forum.unity.com/threads/screen-width-is-wrong-in-editor-mode.94572/
this dates back to 2011 and it's about EditorWindow script. In my case, I have a simple MonoBehaviour that is Executable In Edit Mode and which creates a new Texture with the size of the player screen (at least it has to)

Code (CSharp):

1.  
2. [ExecuteInEditMode]
3. public class SomeMonobeh : MonoBehaviour
4. {
5.    private void OnEnable()
6.    {
7.        var width = Screen.width;
8.        // width is correct when playing, or when adding the script to the object for the first time
9.        // BUT it refers to the size of the INSPECTOR window when manually clicking the "enable/disable" checkbox
10.    }
11. }
12.  

width is correct when playing, or when adding the script to the object for the first time, but it refers to the size of the INSPECTOR window when manually clicking the "enable/disable"checkbox. This is quite the contrary to the Scripting API description https://docs.unity3d.com/ScriptReference/Screen-width.html

Is there a way to get the size of the player window in OnEnable method of an ExecuteInEditMode script?

-- Update

Basically even OnEnables are different. It depends what has caused this OnEnable call. If it was due to assembly reload, it returns correct values. If it was caused by manual "enable/disable" checkbox mouse clicking, it returns wrong values. More than that - when first launching Unity it gives 0-0 for the screen size

 

Kinda solved. In my case it was possible to use https://docs.unity3d.com/ScriptReference/Camera-pixelWidth.html instead of Screen.width
