DK2 built in Orientation sensor drifting

Hi,
I am using DK2 with Oculus Home 1.3, without the external camera sensor.
I read that the external camera sensor would track position but also help with tracking orientation.
But I assume even without the camera sensor, DK2's built in gyro and magetometer should provide stable orientation.

But the DK2 I am using is occasionally drifting horizontally at quite a high speed.
And I think the drifting, and the drifting speed happens depending on what the orientation the HMD is in.
Is this normal because I am not using the camera sensor, or is it because the sensor of the DK2 is defect?
Thank you.

I believe it's a limitation of the gyroscope technology. All headsets that are IMU-only have yaw drift. More info on this wikipedia article: https://en.wikipedia.org/wiki/Inertial_measurement_unit#Disadvantages
