Mavic 2 Pro, gradually tilt rolling to the left on hard left right, left right, left right, left right, left right etc. commands.  I've tried it in many areas and 180° directions.  Same thing.  I think it's too "soft" and needs a bump on the gain for better holding.

It gradually always tilt rolls to the left when going left than going right.  Going right, it roll tilts to the right too but not as much but going back and forth makes it keep rolling to the left, but then resets itself when you stop moving it.  The P4 remains solid.  I'm not sure if the Zoom does it too but I know it always has a left tilt no matter what.  I've tried the calibrations numerous times and it still does it.  I'm not sure if it's because the gimbal motor is on the left side and it's a design error by making the computer think it should be equal left and right with no sort of bias compensation.  Can DJI add some roll bias or increase the gimbal motor gains on the next firmware update?  In fact, I think all the DJI drones need some sort of gain compensation for where the motor is as it is on the left side so the weight isn't the same for both sides.

With the Phantom 4 Pro V2.0, it's way way more heavier on the motorside but if we can have this sort of compensation for the Mavic 2s, our footages would not have tilt.  : )

I need to try doing the compass calibration the other direction to see.

Not quite a noticeable but yes, it does.

Usually right to slightly left on braking

I've fixed it by adding 0.2 roll compensation.  Fixed it completely.

Good to read Ant - I'll give that a try!

The real question is how to reset the gimbal camera after you've messed with it on the screen drag.  There is no way to tell where the center is.

I think the bottom-up button fixes it.

Use the centre points

It's not fixed.  The problem still remained!

My Mavic 2 Pro worked perfectly and had no tilt - until it got exchanged by a serviced model (had issue with the front sensors). With the new model the horizon tilts by about 0,2° when I go left and just a bit less when I go right. I'm wondering if it is a hardware problem in the drone since my first model didn't have the issue.

I've calibrated the IMU somewhere else and I think it fixed it but I'm not sure.  Also calibrated the VPS.

Wind, sports mode can have an effect, My p4p is really bad, yours is nothing compared to the P4P, i even changed the gimbal motor and it made no difference at all, with the p4p, its the gimbal maxing its tolerances, so i was told, i struggle to go with that myself, if that is the case, then it should do it both directions, not just the 1 and its always the same 1, right...

Calibrate the IMU somewhere else to see if it gets fixed.

The Inspire 1 Pro (X3) has super bad tilt when rotating hard.

I have the very same issue, even when I fly really slow. Could it be a firmware thing?

I think it could be a parameters thing.  Something, gain wise, needs to be upped but I'm not sure what to mess with.  I've upped the gain on the X3 camera and that made a big difference.

I also have a strange behavior with our second drone.
In you fly straight forward all is ok gimbal is pefect horizontal but if you fly fast to the right it rolls to right anddoes not go back even if you fly to the left
its the same in the other direction. but if you fly forward when it is rolled it will go back to be horizontal
here you can see. btw i did all the calibrations

Can someone with a proper response on how to fix this say it?  It can help everyone else but I assume it's at the parameter setting.  Mine is the same but tilts to the left.

The only solution is to use the P4PV2.0.
