Description

System Information
Operating system: Windows-10-10.0.17134-SP0 64 Bits
Graphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 442.92

Blender Version
Broken: version: 2.93.0 Beta, branch: master, commit date: 2021-05-27 15:12, hash: rBba4228bcf77e
Worked: 2.92 official release

Short description of error
Rendering in Eevee results in occasional fireflies/white pixels, mostly on the edges of a surface - even with the default material.
Only way to fix is to enable 'High Quality Normals' in the Performance tab under Render Properties, which makes it essential to use.

Exact steps for others to reproduce the error
Open blend file and render F12.
If result is like attached image, pixel shows up at the center.

Enabling 'High Quality Normals' (Render -> Performance) will make it disappear.
