Blender Version
Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-03-20 21:00, hash: 9ca67c47a1
Broken: (oldest archive I have where it is broken) blender-2.93.0-f117ea262463-linux64 March 5

Short description of error
Glitch when rendering with EEVEE

Exact steps for others to reproduce the error

  • with new installation/configuration file and default startup file
  1. Rotate default cube on X axis -28.85 degrees
  2. From compositing tab, add a denoiser node
  3. Render eevee render glitch.png

Also tested this on an Alienware laptop with same results (specs for that not uploaded as it doesn't seem to be hardware dependent).

Problems seems to be related to the angle of the cube side in relation to camera - if you rotate cube intervals of 90 degrees on X axis in either direction problem and render glitch is still there. If you rotate cube just slightly on X axix (from -28.85), problem goes away.

Glitch mostly goes away if you remove the tickmark on HDR box in Denoise node - but there are still a couple of white sparklies if you look very close.eevee render glitch (no HDR on denoise).png

Problem does not appear when switching to Cycles.

Can confirm.

This might be a duplicate of #86578 (white artifacts in EEVEE), but will confirm for now.

I think I'm experiencing the same issue. Random white pixels pop-up on my ground plane. (build: 2021-03-21 18:49 - Windows 10, NVidia GTX980TI)

Don't know if it is the same problem but I also have white pixels in my scene:

It get worse with Camera DoF:

Here is a simple file to reproduce the issue:
eevee_nan_pixels.blend
I have this problem in all Blender versions 2.80->2.92.
I'm on Linux Debian 11, Nvidia GTX 1060.

Having the random white pixels too on Windows 10, Nvidia RTX2060.
They can get way huge when using Depth of Field, jittered or not.

Never had this happen until 2.93.
Since this only occurs at the outline of the geometry relative to the camera, I have a feeling this has to do with 06492fd619?
(The HDR-Denoised output from the OP looks like extremely bright fireflies though)
