Worked: (newest version of Blender that worked as expected)
Short description of error
when trying to apply a lava like material to some basic geometric shapes(CgMatter tutorial) there are Green and White artifacts everywhere on the model. Using the emission node with any color causes it and when using adaptive subdivision using Cycles. I have also had some crashes while doing some stuff with adaptive subdivision on.
Exact steps for others to reproduce the error
have an AMD RX5700XT and try to render the blend file in shading view(adaptive subdivision, emission node.
Adaptive Subdivision turned off
Color node muted
