Is this a compass issue?

The one thing that jumps out at me is the tune.

It’s more a wonder that it is not all over the sky.
Compare your desired to actual in ATT

Have you autotune this craft?

GPS could have been better. Only 7 sv count for the start of your flight.

Thank you @mtnsurveyor but I don’t think low satellite count is reason of yaw changing.
