MPU9250 heading is slowly drifting

[mgrouch]

I also have issues with calibration
windows on 7” display 480x800.
They do not fit. Many input fields
below the graphical part with rotating
compass are not accessible.

Same issue in sizing in OpenCPN creating
a new config template.

Thanks

I have a 19" monitor & still cannot see the lower input fields either - even after resizing the window.

Did you try instead of resizing window resize just graphical area where compass plane is?
I think it could be resized too. 

Thanks
