if you set the value too high (Gain or Exposure), then the node (Emission) produces artefacts in the form of a black glow

My CPU and GPU are fine in other renders it works fine but this is definitely a problem in LuxCore

Why did the cube turn black if, in theory, it should only be lighter?

OS: Windows 10
Blender version: 4.0.2
LuxCore version: 2.8 alpha1

By the way, I forgot to say that this applies not only to objects, but to all light sources.

If you overdo it with brightness, there will be strange effects
