Apparently is an issue with VR template and stereo instancing:

This still is a present bug on UE5.0.3, the only way do get the artifacts away is by turning instancing stereo to disabled, in any optimized VR template settings. This needs to be fixed.

Hello, I have exactly the same problem in UE5.1, lightmap density in viewport showing black lines when moving the viewport view.
I opened a blank game project and problem is still there even when turning off the option VR stereo instancing. Any solution?
