So my first post will be about annoying bug I encountered after upgrading my PC with Radeon GPU card. Specifically – RX 580. But as I understand you can have this bug with all Radeon cards.
After installing Blender 2.83.10 (I’m always after those LTS versions) and starting a new project I get this:

when I chose Material Preview in Viewport Shading menu.

So to fix this problem you basically have two options. First is to install AMD Radeon ProRender for Blender. But unfortunately it is slow… You can use it, but I personally dislike this option. Anyway, after switching to Rendering window:

and choosing AMD Radeon ProRender as your Render Engine

you can see that Material Preview now works.

But try rotating your cube, your model and you will see what I mean.

It gets glitchy, you need to wait for a second for the model to render properly.
Another option is to turn on High Quality Normals. So get back to Rendering window.

And choose Eevee as your Render Engine.

Then scroll down to Performance

and check box next to High Quality Normals.

Get back to Layout window, choose Material Preview and it works like it should work.

So yeah, that’s it. I hope this post was useful to you, another Blender user 🙂 Thank you for visiting my website and… last piece of advice. If you want to do 3D modeling, buy NVIDIA GPU card 😊 Is that simple. Because with Radeon cards while doing 3D modeling I can say for sure you will be running in to small glitches and bugs. Maybe they will not be a deal breaker to you, but they will be definitely annoying.
