Instances are created with an "index" parameter used for persistence over time through animation. Currently the geometry nodes instancer passes the index in the array for this value, but the arrays created by the "Point Distribution" node aren't necessarily stable in this way when the input mesh is deformed. In D9832 we already mostly solved this problem with an `id` attribute. The solution here is to create instances with this attribute as well. It's important to note that deforming the instanced points *after* distribution will usually be a better solution for this problem. This solution is likely still important though.
