I am beginner with blender and I'm currently trying to create some liquid (coffee for example) inside a cup. The cup is not a problem, shading of the liquid is.
I've tried to follow few tutorials on Youtube and always end up getting the same 'bug'. When I set any volume properties (volume absorption, volume scatter), these weird pixelated rectangular shapes start appearing and they flicker a lot when you rotate the view.
I've just added new material to the liquid, set the transmission to 1 and roughness to 0.01. Then I started playing with the volume absorption and after that it starts happening.
- Rendering engine used is Eevee
- The more density, the more it is flickering and overlaying other objects
- It still appears if anything else besides the "liquid" itself is invisible
- It appears both in view mode and in render result

I'll be glad for any advices since I wasn't able to google this specific problem.
