I'm sorry, but I'm not sure what you are referring to.

Could you be more specific?

The problem as the following :

1-I have simple scene which have number of objects and shaders.

2-I need to move or scale one object so I activate edit on preview 

3-when I do that the preview screen show strange screen as in the first screen shoot

4-when I deactivate the edit on preview the preview window show the correct scene 

I suspect you see the editing handles there, but in huge size.

- Have you changed Handle size in File / Properties / Scene Editing before?

or

- Do you use an orthographic camera with a very small Ortho Size?

1-no

2-maybe yes I don't know currently 

We still having this problem but it seems that when user select some shader the preview window show these strange colors like the following video.

We use aximmtery 2020.3 and P2000 gpu card

I still think that they are the 3D editing handles.
Normally it looks like this:

But if it's size is too big for some reason

it becomes an ugly one:

Another reason can be, that the handle is set to be non-constant size:

and there are unit problems in your scene. For e.g. the sizes are not converted from centimeters to meters during the import.  Or the object are too small for some other reason.
