Thank you for the advice, Martin! Changing the Resolution & Steps definitely had an impact. Steps was set to 64 and I had to raise it to 128 for it to begin to improve. Switching the Resolution from 1:8 to 1:4 helped as well. Naturally, the FPS of playback slowed dramatically. When I tried it with Cycles, the pattern went away.
Does the end result of the same EEVEE settings (ie Steps = 64 and Resolution = 1:8) differ significantly from one GPU to another? Both my desktop & laptop are older, so I haven’t tested it with a newer tech.
