This is normal to all cameras. Essentially it means that SGP believes that your image should be complete but the camera is not reporting it to be complete. For the most part these are beguine.
If it's an ASCOM driver it should work fine. But why would this be preferable to the SX supplied driver (which also uses the native SX drivers). Seems like you'd be adding complexity and another piece of software to trace through if things go wrong.
It should work, but sounds like it could be problematic.
