This is the log on my Dell with 2 graphic cards, Intel and Nvidia: I have the opencl version of LuxCore and Linux as operating system.

I should not press that button ;) but I think that the error should be handled,
It is an internal error of the Intel GPU driver, it is the kind of stuff that can easily crash the entire OS. I doubt that it is possible to recover from that kind of error.

It is the lighting used to compute indirect light contribution: you can think to this output like a version of the rendering with large pixels (or a minecraft version, etc.).
You may need to trace more photons or reduce the radius, if the image doesn't looks "right": for instance, there are some large difference between near "spots", the "spots" are too large,etc.

Those spots look good enough to me.
Spot size is defined by Lookup Radius, and more Photon Count means smoother look, or less difference between adjacent spots.

But for your original scene it was easy to spot ;) the problem with Show Indirect Debug Mode:

In the latest BlendLuxCore, Intel integrated GPUs are disabled by default to avoid these kinds of problems.
