Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-03-16 22:45, hash: rBde06cb85593b
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.
