Distant shore foam and waves jitters and flickers when using TAA
Describe the bug When viewing distant shorelines, the shoreline foam flickers and jitters. You can see it in this video: https://www.youtube.com/watch?v=EEBr6L6NYkg&feature=youtu.be
Built-in Pipeline, 2019.4.4
It's extremely evident in the central pond area, but it's actually an issue all around the shore if you look closely.
It doesn't just seem like LOD or such, it seems to rapidly switch back and forth between different foam positions, creating a flickering effect.
Someone else has experiences this problem on Discord. They are using Enviro. Are you also using it? It might be related.
Yes, I'm using Enviro. Glad you have a lead! Eager for a resolution!

Would it be possible to test with enviro disabled, to confirm that is the issue?
From user Jamison on Discord:
So I was able to get rid of the flickering by turning off the Anti-Aliasing on the Post Processing component added by Enviro. I'm still working on adding Anti-Aliasing that doesn't cause flicker for me. If I use FXAA or SMAA instead of TAA the problem goes away
I believe I have the solution -- I am still using TAA for Anti-Aliasing, as FXAA and SMAA aren't feasible in my case. However, by lowering the "Jitter Spread" on the Camera's Post Processing "Anti-Aliasing" section from the default of 0.75 to 0.35, the shoreline jittering effect has been eliminated.
Thanks. Glad to have a workaround. I believe (hope) this can be properly fixed by supporting motion vectors. It is on the list, but not a high priority.
