FLICKERING PCG SPLINE MESHES UNREAL ENGINE 5 VR

we are trying to create splines to procedurally create static meshes, for example fences.
The issue we are facing is that the meshes start flickering upon rendering in VR preview with Android Vulkan turned on.
Its happening both in our own project in 5.3.2 and in a new project in version 5.4.4
