Short description of error
Program keeps on crashing unexpectedly. Sometimes buttons of the Blender UI are rendered badly (see screenshots). Objects are not displayed/almost invisible (dark grey), when using the "Material Preview" and "Render Preview" mode in the 3D-Viewport. (see screenshot).

The default Cube in the default startup file in "Rendered View Mode" after orbiting a bit:

Usually blender crashes when the GPU is at its limits:

Exact steps for others to reproduce the error
Happens to me on default startup file. It does not crash immediately but on random events (e.g. clicking random buttons) / orbiting/ zooming in the 3d-Viewport (mostly when using Rendered Viewor Material Preview) and almost always when rendering (except rendering from command line without using the UI).

Thank you!

There have been various reports of rendering issues with AMD GPUs in Blender after recent driver updates (20.11.2 and beyond). From the looks of it, you are experiencing this issue. There are a few ways to work around this:

Try downgrading your GPU drivers to a version prior to 20.11.2 to see if it helps.
Try enabling High Quality Normals in the current version of Blender you have (Render Properties -> Performance -> High Quality Normals - See image below). It should be noted that enabling High Quality Normals will not resolve rendering issues for all object types in Blender unless you're using Blender 2.92+.
Try downloading the development build of Blender 2.92 or 2.93 which includes a fix (High Quality Normals enabled on all object types): https://builder.blender.org/download/

For reference, we keep track of these issues with the drivers in #82856. I will be merging your report into that one.

Thank you for your swift response!

For the record and future reference:

I tried these versions with no success:

Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-01-19 22:43, hash: 6290091bac
Broken: version: 2.92.0 Beta, branch: master, commit date: 2021-01-19 17:58, hash: c2e6969c56

Enabling High Quality Normals

in the current version (2.91.0, branch: master, commit date: 2020-11-25 08:34, hash: 0f45cab862) did resolve rendering issues in the Viewport, but Blender still crashes when I try to render.

2.93.0 Alpha and 2.92.0 Beta: the 3D-View is sometimes blinking black (except objects) and parts of the words/menus are missing in the UI (Screenshot).
I did downgrade the AMD driver to 20.10.1 and it works fine.

I'll follow #82856 to keep updated.

Thank you again for all the work you're doing. It's amazing how I get an answer in hours from a community-driven, open-source software project while all the bug reports I filed all my life for big Corp software seemingly ended nowhere and were never to be heard of again.
