We are currently getting many reports about graphics glitches with AMD graphic driver versions later than 20.11.2, see #82856.
Please open Blender's installation directory and double click on the
blender_debug_gpu.cmd. This will start Blender in debug mode and create log files. Try to make Blender produced the glitches again. Once it does, close Blender. The Windows Explorer should open and show you up to two files, a debug log and the system information. Add them to your bug report by clicking on the upload button as shown in the screenshot below or via drag and drop.Added subscriber: @gevorgsargsian

Hi! I met the problem too. I currently have blender 2.91. First I find about this bug was in blender 2.83. I taught a new version can solve this problem but it didn't.
There are some pictures. Might those help too. Looking forward to your answer.
(Sorry for my englis and if this comment is not how it needs to be)
I downgraded my videocard's driver but the problem is still there.
@TheCreator19 Please make sure that you are either using version 20.11.1 of the AMD graphics driver or enable Render Properties > Performance > High Quality Normals. You can also test a daily build of Blender 2.92 that contains a workaround for this problem. If none of these solve the issue, then please create a new bug report for your problem.
Yes I downgraded once more now I'm using version 20.11.1 and it is working. Thank you for ypour quick answer. I really appreciate it!!! Sorry if my commet sounded like a dick or something (I just don't now how to express myshelf in englis). I truly thanks.

So. The materials preview is showing just grey silhouette. While in eevee the "high quality normals" method did the job. But what about Cycles? I am using Blender 3.4.0. Initially happened with Blender 3.1 so to solve the issue I thought of installing the newer version but that didn't help. Please help me solve this issue.
