The initial Gyro calibration happens straight after poweron, before the system warms up… So try powering on, letting it warm up a bit, then repowering" https://discuss.ardupilot.org/t/pixhawk-2-1-gyro-and-compass-problem/12936

try a pre-flight reboot or pre-flight calibration via MissionPlanner and see if that helps once temperature is stabilised.
