Yes this is a short coming of the math method used. Note that the cursor should also be restrained in the vertical direction so as to not wrap from the top to the bottom, or visa versa, not doing so potentially compounds the confusion Put simply the matrix math used supports a 'restrained' cylindrical viewer not a true spherical viewer. The reasons that FlightGear does not use a quaternion model for this, I will leave for others to explain.
