In VR, eyes sometimes show different LODs when you are exactly at the edge of a LOD transition. It then looks like this:

In this test I spawned many static meshes where LOD0 is a cylinder and LOD1 is something that looks significantly different than a cylinder. You see that the left eye sees LOD0 while the right eye sees LOD1.
This feels very, very bad in VR.
Reproducing this is very simple since the only thing you need to do is add a static mesh somewhere, set the LOD screen sizes up so that you can clearly see when a transition is happening and then just move to exactly where that transition happens in VR and move your head back and forth. You will see the mesh transitions LOD on either left or right eye first, and then once you move your head a bit more the other eye sees the same LOD again.
I also uploaded the repro project where I tested it with [here][2].
Its the project you see in the screenshot above, controls are same like in the VR template.
