version: 2.80 (sub 41), branch: master, commit date: 2019-01-16 21:59, hash: e57ee5934a, type: Release
Short description of error
Maybe I'm the one who mistakes the procedure by adding the subsurf in the fluid domain
If I add the subsurf at fluid domain the motion blur disappears

Exact steps for others to reproduce the error
I recorded a video

It would be good to support this, but the fluid motion blur system is too limited for that at the moment. It's a known limitation currently.
