Can confirm.

I guess by now there are a couple of duplicated reports around, will try to merge these all, but for now, will confirm.

Yep can confirm also, even a value of 0.01 in roughness will temp fix it or turning on Ambient Occlusion in Render Settings seems to fixes it also.

HDRI Preview Spheres are also effected.

Some observations:

The bump node has nothing to do with it, disconnecting the bump node doesn't solve the issue.
No Subdivision surface modifier.
The specular light pass is where this issue appears.
Roughness of 0.00002 no issue, roughness set to 0.00001 shows the issue.
Turning on ambient occlusion does solve the issue, as stated above.

Since that last four points are different than in #86578 (white artifacts in EEVEE), I think that these two reports have different causes.

The clearcoat roughness shows the same effects as described by Evan Wilson for roughness above.
May be this could help to narrow down the piece of code...

Seems the bug is fixed in today's windows build for me.
Yesterday: full blown white model with 0 roughness shader, also full blown white metal hdr preview sphere.
Today: everything works fine. Ambient occlusion is disabled.

Confirm, no bug in this build for me.
Windows 8.1, nVidia

Issue is resolved for me as well.

I will close this as resolved, if issues are persistent for anyone here, please open a new report since the issue would be even more specific in that case, thx.
