Canvas does not display correctly in Scene window

I have recently had this problem on my main computer only and on different projects.

If I copy a project to my old desktop or laptop there is no issue.

I create a canvas on any project and add elements such as Text or a Button to the canvas, in the Scene window the only item displayed is the currently highlighted element see the attached screenshots of the problem and then from any other computer.

The Game window displays all elements correctly, I can only align the objects correctly by using the Game window as a guide and no text displays within the Text box or Button on the Scene window whether the element is highlighted or not.

I have uninstalled and reinstalled versions of Hub 2017 and 2019 and still have the same problem.

Any ideas?

Thank you but neither suggestion helps.

If you check both images I posted you will see that from different PC all looks good.

Hello, thank you for your reply.

I have an NVidia graphics card this computer, I have upgraded the graphics drivers on the motherboard and the graphics card since your reply and am still confounded by the same problem, a real head-scratcher this one.

Gizmos the same on both.

Removed graphics card and running on MB graphics… same problem.

Only thing I can think of is to reset windows 10 and start again but there is no guarantee that would cure the problem.
