System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: Radeon (TM) RX 480 Graphics ATI Technologies Inc. 4.5.14757 Core Profile Context 20.11.2 27.20.14501.18003

Blender Version
Broken: version: 2.91.0, branch: master, commit date: 2020-11-25 08:34, hash: 0f45cab862
Worked: (newest version of Blender that worked as expected)

Short description of error
When trying to use viewport shading with render engine Eevee, or with render engine set as cycles with GPU , all objects render as shown [here ]] and [ https:*imgur.com/a/kLLQSIJ | here . I am including a system info file.system-info.txt
I've tested this with blender 2.79, 2.8 , and my current 2.91.0 version, with the same result. I've tried updating AMD drivers, rolling back to the previous versions, system restore, but the issue prevails.
Exact steps for others to reproduce the error
This happens with every object I open or create; even the base cube.

The graphics driver version 20.11.2 is known to cause issue (see #82856). Please test if enabling Render Properties > Performance > High Quality Normals avoids this issue. Until the problem is resolved I would suggest you downgrade to 20.11.1.

I tested this without downgrading.
Enabling Render Properties > Performance > High Quality Normals indeed fixed this issue. Thank you very much!
