Short description of error
When Volume Absorption is on and light is on render has boxes in final product.
Exact steps for others to reproduce the error
Use both CPU & GPU for rendering.
If I use just CPU or just GPU, there are no boxes; with both, boxes. I added an image of my preferences. Also a video of the various settings and the render.
In Material tab scroll down to Volume, add Volume Absorption, Render Image.
