Looks like it is still a thing with instanced meshes and foliage...

I am having this same issue in 4.25 but only if lights are casting ray traced shadows, turning that off fixes the artifacts. I still have other RTX features enabled like RT reflections and GI.

You can still do wind effects, just not with world position offset.

Currently raytracing doesnt have support for materials that have world offset. Aka remove the wind simulation and it will render fine.

Hm =) And if I need wind simulation - I should turn off the RTX? =) crazy situation =) But thank you for the answer.
