Thank you all to answer.

I'm in ONYX2 IR 2 on 6.5 with 3 pipes.

Phil Keslin said to me that it's a bug, I think so because I'm not this gap
on my old RE2 on 5.3

Marc Simon said that I have to genlock my pipe and use the swapready. I have
genlocked with horizontal rate but I haven't use the swapready ( how you
configure it ?)

Rob Jenkins said that the frame boundary can cause this, does exist some
optimisation for that ?
