Resolution Note (2019.2.X):
The Variant prefab have overrides for the m_LODs.Array.data[0].renderers.Array.data[0].renderer that causes this flickering (wrong renderers are overridden in the Variant).
We cannot know how these overrides got there in the first place (user action or old bug), but we have verified that when making a new Variant from a the good version no overrides to the m_LODs.Array.data happens in recent released versions.
The workaround for these Variant prefabs is simply to open the Variant in Prefab Mode and then revert the LOD Group (in the Overrides window or on the context menu on the LOD Group component). This brings the LOD Group back to match the base prefab.
