lenovo ideapad 120s, intel pentium
Operating system: windows 10
Graphics card: intel integrated graphics

2.93
Broken: (roughness channel at 0 turn black)
Worked: (everything except this)

when i turn roughness to 0 it becomes pitch black like there is no shader connected to the output. the hdri sphere on the bottom right is black like the material at 0 roughness

just turn the roughness to zero on any color
Based on the default startup or an attached .blend file (as simple as possible).

I could not reproduce, I suspect it may be outdated drivers/hardware.
Also, moving the task out of purgarory, careful with changing status, let triagers do it.

Guess this is duplicate of #88754 (Intel HD graphics: Changing Roughness Value to 0 causes mesh to be black)
