Unreal Engine Issues and Bug Tracker (UE-88319)

Description

Rendering artifacts when using spline meshes with Vulkan enabled.

Recent Nvidia drivers may be required for repro. (Users version: 441.66 , My Local Version: 441.12)

Confirmed in MAIN 4.25 @ CL 11289608

Steps to Reproduce

In project settings - Change Default RHI to Vulkan and restart editor
Place a Spline Mesh Actor into scene and assign a static mesh (Not very apparent with cube, try cylinder or sphere)

Result: Black rendering artifacts reminiscent of z-fighting
