Hmm, I tried cropping the image to an area where this appears, and process that, but it doesn't happen. So I guess you'll have to go with my full image:

Simple steps:
--- Auto Develop
Parameter [Ignore Fine Detail <] set to [Off]
Parameter [Outside ROI Influence] set to [15 %]
--- Bin
Parameter [Scale] set to [(scale/noise reduction 50.00%)/(400.00%)/(+2.00 bits)]
--- Crop
Parameter [X1] set to [32 pixels]
Parameter [Y1] set to [32 pixels]
Parameter [X2] set to [2569 pixels (-32)]
Parameter [Y2] set to [1700 pixels (-32)]
--- Wipe
Parameter [Mode] set to [Correct Color & Brightness]
Parameter [UNKNOWN] set to [No]
Parameter [Precision] set to [256 x 256 pixels]
Parameter [Dark Anomaly Filter] set to [4 pixels]
Parameter [Drop Off Point] set to [0 %]
Parameter [Corner Aggressiveness] set to [100 %]
Parameter [Aggressiveness] set to [75 %]
--- Auto Develop
Parameter [Ignore Fine Detail <] set to [Off]
Parameter [Outside ROI Influence] set to [15 %]
(auto develop without ROI - hey perhaps you should store the ROI rectangle in the log for cases where it might matter!)
And then I press decon, say yes to the auto mask and at the default settings I get little white pixels. They vary and even disappear if I alter the settings (e.g. move to "more noise")
By the way, is there a way for DSS to produce autosave TIF (and not FITS) without zip compression? Or, otherwise, perhaps there is a zip library that is easy to integrate so that startools can read those TIF files directly?
