Short description of error
Eevee bsdf shaders glithces when rendered and in viewport

Exact steps for others to reproduce the error
with basic startup assign a material on the cube and add to volume setting some of the bsdf effects and it appears as a smokey green pixelated curtain front the object, more like an artifact

additional: recently i upgraded to ubuntu focal fossa 20.04, but i can't directly relate this issue with this because the last version of blender i used before this doesn't included eevee engine

Could you provide a simple .blend file demonstrating the problem?

a lot of volume shaders cause such glitch. glossy BSDF, glass BSDF, velvet BSDF, translation BSDF, Toon BSDF, subsurf scattering,
