QHY9 Overscan Correction Errors.

Has anyone else turned on overscan correction in their qhy9 driver? I honestly don't see any improvement but I do have intermittent problems getting flats to combine.

I have a couple of nights worth of RGB here and if I include the flats for each filter into the calibration I get crazy results. Like the top half of blue is missing, red and green are black and Lum looks like wool off a sheeps back I am using maxim here.

The flats look fine to me and when I combined Lum in deepsky using the same CAL files, the result is as expected, ie: not wool.

I'm at a loss and have tried pedistal settings, masters etc, but just don't understand why it is so. Any tips? I seem to get this occasionally whenever I try out overscan correction.
