System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: AMD Radeon RX 6800 XT 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: 2.8x (has similar visual artefacting, might report that one later)

Short description of error
Faces flicker in edit mode on all objects (any objects, really) except the default cube. Video down below shows the exact behavior. AA being enabled/disabled does not make a difference. Modifying the clip start/clip end values does make it somewhat less prominent, but only from a certain distance from observed objects.

Exact steps for others to reproduce the error
default startup file > duplicate the default cube > enter edit mode with one of them selected

Have a nice day

There has been a lot of reports lately with 20.11.2 driver version and RX 4xx/5xx GPU's. So this may be problem in this case as well.
We don't fix 2.8x versions anymore apart from LTS that receives only critical fixes.

Please check if you can downgrade driver or try Radeon Pro Software for Enterprise 20.Q4 which works fine on my machine.

Took me hours to figure out:
Disable "Fade Inactive Geometry"

I think it's an issue with the graphics driver + blender doesn't handle it well. (Just upgraded this week to AMD 6800 XT driver 21.2.1; blender 2.91.2 ; never had the issue on AMD rx 570)

Blender + AMD please fix Q____Q
