Landscape tearing

I’m getting some severe flickering on parts of my landscape. What exactly is happening here and more importantly, what is the solution?

The landscape is using displacement (e.g. using nanite), which appears to be the cause of the problem. The top portion of the image is Lit and the bottom half is Wireframe. I’ve noticed this issue seems relegated to the edges of the Landscape topology. It is not visible on every single edge; only some of them. Furthermore, the issue also appears to be at least somewhat view-dependent.

Any help would be appreciated.

I was able to solve the issue by Enabling the NaniteSkirt and setting the NaniteSkirtDepth to a valve of 0.0 (the default is 0.1). While enabling NaniteSkirt made a small difference, setting the SkirtDepth to 0.0 is what really solved the problem.

I can only speculate why this works as my cursory searches did not turn up any documentation about these properties :frowning: As such, I cannot say if these settings will cause any other landscape issues in the future. I can only say that for now, on this immediate issue, they appear to have solved the problem.
