Circle artifacts on indirect illumination

There are visible circle artifacts on the sphere in the Sponza scene.
Here is the video with varying shininess:

At first, I thought that this artifact comes from the method itself due to the discretization of the scene and directional sampling, not the implementation bug. But I couldn't figure it out the direct cause and couldn't find anything related to this problem from the web as well.

So I need some opinion on this problem.

Thank you.

Rendering difference between Windows and Ubuntu

While migrating to Ubuntu, I found that there is a big difference at GI rendering result as you can see from the two images below. I used the same code and configurations, hardware and no error appears in the output.

linux
windows

I'm still trying to figure out what's the causes of this problem. Any comments would be helpful.

Thank you.

Hi, size_t is missing when compiling, you need to include into Pool.cpp
