Hi,
just look a bit around in the forum or the news page
That's a known Chrome issue because since Chrome 66 the gyroscope sensor data values were changed from radians to degrees - and these 'larger' values are causing the hyper-senstive gyroscope movement.
Since krpano version 1.19-pr15 the gyro2.js and webvr.js plugin are updated to handle the values from old and new Chrome versions:
krpano 1.19-pr15 / pr16
That means just update to the latest krpano version (e.g. using the update tool).
Best regards,
Klaus
