Rigid bodies get stuck during simulation

[deathproof66]

Hello! I have encountered a problem with the rigid bodies in my hybrido simulation. I want some fruit slices to move with the fluid so I made them as rigid bodies and dropped them into the fluid during the simulation. The problem is that the rigid bodes seem to get stuck now and then for a few frames until they start moving again. I am simulating in slow motion (500fps) and have tried min: 100 max: 333 for the subdivisions as well as higher and lower numbers. The problem remains. Any ideas on how to fix it?

Here is a video preview of the problem:

I hope it makes sense. I would appreciate your help.

The issue is quite weird, honestly.

Which RealFlow version is it happening on?
Can you test the same scene on RealFlow 10? (The demo should do if you are using RealFlow 2015)
