You mean the whole OS becomes unresponsive? Can you describe it in more detail?
This usually hints to a problem in the GPU driver or OS itself. A mere user-executed program like LuxCore doesn't have the power to freeze the whole OS. You could try to update your drivers.

Looks fine on my side, using latest BLC 2.5b1 on B 2.91

The problem was hidden in the AMDGPU-PRO Linux driver.
I couldn't make it work by any effort.
On Windows, the AMD driver completed the task without error.
Thank you all for your participation

The adventure continues. I can't handle the question.
If there is Band in the material at the Bump input, then various artifacts occur. For example, when rendering with tiles:

Here is an example artifact file:

I have tried all drivers on Windows and Linux.
Could it be my graphics card? Or does this happen on all AMD video cards?

Yes, it is an AMD-only problem:

Thank you for your reply.
I reconfigured the materials and everything works great now.
