Hi,
it is because of the high vibration of your drone
follow this link to reduce the vibration
make sure the motors and props are parallel to the ground. Take a look at this link
calibrate the sensors of the flight controller in the test field
here you can see the accel clipping as stated in the log file.
The reason is mostly phisitcal so try to fix that.
If you did everything mintioned and you still have vibration you can reduce IMU_DGAYRO_CUTOFF to 20 or even 15Hz and ** IMU_GYRO_CUTOFF** to 30Hz if thats help.
Best,
