Has anyone else noticed some severe anti-aliasing issues in 5.3?
This seems to only happen when using Temporal Anti-Aliasing or Temporal Super-Resolution.
It occurs when a landscape has a material with a WPO node attached that is not 0.
Its even worse in 5.4.

Is that actually a landscape actor, or a mesh ( sphere )?

It goes away when enabling nanite on the landscape and building it.

I did this and it did not fix the issue.

This only occurs on landscape actors.

Has anyone found a solution?
