System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 457.30

Blender Version
Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-03-16 22:45, hash: de06cb8559
Worked: (newest version of Blender that worked as expected)

Short description of error
Since a version some days ago (i cannot tell which exact version) i am getting white pixels on some objects in some scenes in eevee.
I haven't been able to narrow it down to a single parameter.
It seems to happen on flat angles/ borders.

There are things that sometimes make it worse:
in material high glossiness, low roughness, normal map (but even happens without)
reflection plane seems to make it worse
in render settings: high sampling, half res trace, no high quality normals, max roughness

Exact steps for others to reproduce the error
I have attached a blend file which shows 1 pixel as white. in other scenes it's more obvious.
test.blend

@EvaVomhoff , thanks for the report . I don't see any white spot on rendering ( tested on version 2.93.0 alpha hash : de06cb85593 date : 2021-03-16 ) .

I can reproduce the result on my PC with nVidia RTX Cards, but not my Laptop on Intel Iris GPU.

This is probably a duplicate of either
#86578 (white artifacts in EEVEE)
#86604 (EEVEE roughness 0 results in bright white material)
#86614 (Eevee: Transparent material goes superbright with clearcoat-/roughness set to zero)

I am getting the white pixel as well

Like I said, the mentioned reports above might all have the same root, but will keep this separately for now.

All similar reports considering this too occurs with NVIDIA graphic card .
