Short description of error
I'm getting these white pixels/squares/rectangles in my Eevee renders. I've only ever seen it occur on top of particle hair and card-based hair with "hashed" transparency.
During an animation it will only happen on certain frames, and assuming nothing is changed will always appear on that frame when rendered.
The artifacts always seem to be either 1x1 pixel, 1x2 pixels, 2x2 pixels, or 6x8 pixels, and can be affected by depth of field, bloom and other effects probably. One of the frames I've rendered has a blurry white blob about 140x140 pixels.
Exact steps for others to reproduce the error
This is very frustrating because it's happening in a "production" file with many commercial assets so I can't upload the file. I also haven't been able to reproduce it in a simple file. I may be able to trim the file down if necessary.
