System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 451.67

Blender Version
Broken: version: All versions I've tested from the latest 2.92 alpha to the 2.83 LTS
I'm not sure this ever worked, though I personally didn't notice it until recently.

Description:
Studio Lights presets preview icons do not render the 4th light.
As you can see in this picture, the preview icon on the right should look like the sphere in the viewport on the left. But the 4th light just isn't rendered in the preview image for some reason.

To reproduce:

  • Create and save a studio light preset using only the 4th light. Since only the 4th light is used, the preview icon will just be black.

@Jeroen-Bakker IIRC you added these? Would you mind having a look?
Would be good to know if it's a graphics issue or UI code issue.

Looks like a bug to me, but didn't investigate.

Oh sorry to jump in like that, I had the tab open all day and didn't notice the above comments until just now. @JulianEisel it is just a small logic error in the icon generation code, so I'm not sure exactly what to classify this as.
