Animated Xfo Alembic cache generate big motion blur errors

Hi,
I have a geo cache (alembic geo cache) attached to a moving object, this generate big streaks when to object move.

I understand mesh changing topology cause problems but how can I work around with that ?

Same issue here. I know is not ideal but I just have to work with out Motion blur.

I hope soon it would be fix, Alembic geo cache is still experimental.
