When DitheredLODTransition is enabled for HierarchicalInstancedStaticMesh, in the previous version (5.1.1), dithering was applied during fade-in/fade-out, but in 5.4.3, dithering is not applied during fade-out. As a result, the object disappears suddenly.
It's confirmed that dithering works properly again when r.CullInstances=0 is set. So possibly distance culling removes the object before applying dither fade-out.
Based on the discussion in the internal slack thread, this might be an issue.

Expected Behavior: Even in the fade-out scenario, the objects should use dithering.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-221257 in the post.
