Change the last setting, "Duplicate frames removal" to "Do not remove" and try playing it.

I had a similar experience.

I am using rife 4.9 x3 with vsync and it creates a lot of artifacts on spy x family anime. Did you guys try this anime. I thought 4.9 should be better in the frame of artifacts but if i'm not mistaken it is the same as 4.6 with poor gpu performance.

For animation, 4.12 or 4.13 is definitely better.
I've been using 4.12 for animation only.
