Strange twitching with Octo on ground (APM1 with latest 2.3 MP firmware)

After installing the latest MP firmware (2.3) for my octo.
Im getting a strange twitching when i spin up the motors on the ground as seen in the video.
I have tried changing the RATE P and STAB P to no avail.

It however still flies, fairly stable, but still with that strange effect.

Any ideas?

Thanks guys!

It seems to be a bug concerning Rate D.

2.3.1 should resolve this, I hope.

easy to fly but twitches. but dont listen to me, liftoff is your own responsibility.

Liftoff isnt a problem, just gotta do it quick and carefully ;)

I wouldn't fly that expensive looking octo with that twitch going on.

The twitch is more pronounced because its not rigidly attached to the landing gear, but i think I agree with you...
