IPC effects glitch

I am running an iPC with a rock wing controlling 17 mac 2K profiles and a few dimmers. Software is the latest version.

I am seeing a momentary pause in various effect moves or colour chases during playback. They seem to occur randomly. I can have a whole show without a problem or multiple pauses during one show. The pause is very short but very annoying. The effect appears catches up to where it should be after the pause causing lights to jump position.

I have seen various posts that maybe about this issue but no solution. Anyone know hos to fix this?
