“dirty” is a technical term, not a problem. A dirty object is one that needs to be re-computed or re-indexed. Just about everything you do in Roon dirties some things and then cleans them again… Outside reference
I recommend moving away from our legacy iTunes support–we deprecated and replaced it because it was not only the wrong product design, but it also had some problems (including memory issues). There’s some documentation here, and @support can help if you have questions.
