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.

I cannot reproduce the problem.
CPU or GPU render?
I also think that some steps to reproduce the problem are missing.

Both CPU and GPU. 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.

Even though I have a relatively similar setup, I cannot reproduce the problem.
However, this problem is very similar to T73417
I'm tempted to merge the reports.

I looked at the other one, it does seem like there are some similarities. Looking at the artifacts in mine I noticed it seemed to be in the "shadow" created by the light passing through the Volume Absorption, so I moved the light. As you can see by the attached renders, the artifacts move with the "shadow" of the liquid.
