Well, let's try something to see if we can work it out.
1.  Ensure 4 axis are all at the same level.
2.  Check the value in X,Y,Z of GPS location.
3.  Confirm the centre of gravity.

Make sure the motors are level. Even a single degree out of level and it will turn. It's a real down side to the Tarrot frame. On the DJI frames there is no way to turn the motors accidentally. They are all properly aligned.

I have this problem too. So do most people... Sounds like a firmware bug of some sort

Have you solved this problem? I think your IMU may need recalibrating?

I'm having the same issues. I'm very new to the Hobby, purchased an off-brand Tarot like frame and there is obviously room for error when mounting the motors as they are (Tarot like system). So Yaw Gain needs to be lowered rather than increased (100% down to 90%) and make sure the motor mounts are level. It is kind of a bummer when you spend $1300 on a Hexcopter and you start having issues. It has become pretty awkward to fly at times due to this problem. What it sounds like is it's the frame.

It looks like DJI has no business to think about this problem. Got it on my quad also after updating from 3.18. Before the update everything was ok. I have no response from DJI for quite a while on this issue.
I've tried everything, including downgrading the soft and remounting everything on my frame to eliminate any possible magnetic interference - nothing helped.
Its obviously a FC issue, the drone after yawning flies away to the right or to the left (depends on the direction of the spin), than stops and goes back to the point of the rotation (place where it should be all the time).
Im starting to think that they just let go of naza assistance and got focused on the new P3 and Inspire... even A2 problems are left without an answer...

I had yaw issues when my compass was off a tad.  Naza uses the compass to know its heading but once the craft is moving it is able to get heading info from the gps too which is more reliable than the compass so it's possible Naza is trying to adjust for both so the heading matches gps and compass.  My pixhawk flight controller would yaw on me once moving 6 m/s cuz it would start listening to the heading info it got from the gps and when I slowed down and gps heading wasn't reliable it would use heading info from the compass and yaw again. The issue was the cheap Chinese gps and compass assembly I was using had the arrow on the gps puck in the wrong place. Easy to figure out with pixhawk be because when connected to mission planner the copter was facing north in  my bedroom and mission planner was showing north east so I just rotated the gps on the stand until mission planner showed north like the copter was physically facing and that solved my issue..  With Naza there is no mission planner so you have to guess or use the azimuth info off of iosd to get the degrees Naza thinks it's facing and compare it to how the copter is physically facing and turn Naza gps puck until they line up. No iosd then your guessing..  If it's more than 25 degrees off I've noticed is when the toilet bowling will start...

Hope I helped you guys

Mark its not a toilet bowl, it simply runs away to one side after the yaw, than stops and goes back to the point of the yaw. Looks like the gps is getting set to the point cuple of meters away, thac gets a new (old and proper) position fixed again and flyes back in the right place.

I have the same issue here to.

All was working fine, added the iOsd and reflashed everything to make sure all features were picked up and now the qwad yaws to the right and is very erratic.

Spent around £400 of all of the DJI stuff for my custom built qwad and now it looks like it was a waste of money!

Should have gone the tarot route!

DJI, PLEASE SOLVE THIS MASSIVE ISSUE!
