MPU9250 heading is slowly drifting

[Sailoog]

This is my op2 install on RPI4 it is all current as of yesterday. I changed the imu to make sure that was not the issue but no change..  it has been running for 12 hours with little change. pitch is off by about 12 deg but heel is off 90 deg. the number slowly oscillates between -145 and 15 deg on the heal. hitting boat is level does nothing. I did a check to see if i had more then one RTIMULib.ini only one.

Same here
