"Stripes" on the OpenLand landscape in the finished project build.

Hello everyone!
I am using the OpenLand material for my landscape and have a problem. In the finished build of the project, “stripes” appear on the landscape in some places.
For example, on a mountain where I have a stone texture, stripes with a grass texture appear (screenshot 1, 4), and in places where the main grass texture is stripes with a stone texture! There is no bug in the engine in the project itself, it appears only in the build. And sometimes there are patches like this that flicker (screenshot 2 and 3).

I am using Unreal Engine 5.6.1
OpenLand from github.

I’ve tried different things to fix it:

  1. Enabled and disabled Render Virtual Textures.
  2. In the landscape, I changed the LOD settings to the following - LOD 0 Screen Size = 0.1, LOD 0 = 10.0, Other LODs = 10.0, Blend Range = 1.0. And even changed the Max LOD Level.
  3. In the master material, all Texture Samples have Sampler Source: Shared: Wrap.
  4. In the project, in the Config/DefaultEngine.ini file, I added “[/Script/Engine.RendererSettings]
    r.Streaming.PoolSize=4000
    r.Streaming.LimitPoolSizeToVRAM=1
    r.Streaming.MaxTempMemoryAllowed=100”.
  5. Used others landscape materials.

None of this helped =(
Has anyone encountered a similar problem and has it been solved?

I have created a new landscape with these parameters:

There are significantly fewer “stripes” and they are not so long anymore!

I will focus on this option. If someone has a better idea - write!
