    Yes, unfortunately that's not the title I submitted the bug with and it doesn't describe the scope of the problem. Whoever does the bug verification on the Unity side rewrites the bug report for the Issue Tracker with a new title and description.

    I have word now that this is bug is getting worked on.

    The title is a bit misleading, the issue is bigger than just motion blur problems -- motion vectors for indirect instanced rendered objects are completely broken now, unlike previous version.
    This will create issues for things like TAA/Motion blur and anything using motion vectors, it's a big regression
