As can be seen from the above photo, duing my last flight with the mavic the horizon was very very croocked. Could this be cause by either high winds or bad imu calibration (even though I always check signals and they were very low green)? It's was way off that I didn't even try adjusting gimbal roll. Will give it another try soon to see if the problem persists.

Mine was like that at first then I did the IMU calibration and it solved the problem.

As Lucas said, If it persists do first AN AUTO GIMBAL CALIBRATION if still doesn't work then do the IMU CALIB.

There's also a button and wheel combination to manually adjust the horizon, if needed. I'm probably wrong, since I'm relying on my memory, but maybe it's holding down C2 and scrolling the right controller wheel (left or right, to correct the tilt).

this might help

Do you need to zero the Gimbal Roll 1st before doing the Gimbal calibration then compensate after?

In almost a year of flying it happened in one of the earlier firmware version at startup then when I did auto calibration and it worked and then updated to .700 I never had this issue again.

So I am still on.700 with a jailed break one, NO LOGIN, NO UPDATES and enjoying my time flying instead of ....

I double checked, and while flying (or on the ground, your choice), press and hold the C2 button and spin the right RC wheel to adjust the level of the gimbal. It's an easy way to do it on the fly... Excuse the pun!

Thanks for the replies above, and for the OP, please try to calibrate the gimbal or try to adjust the gimbal roll. It will get the issue resolved.

Thanks all for the replies, will definitely give it a try
