Hello @curby, I have reproduced your issue. We will look into it. Sadly, I can already tell it wont be an easy fix. Thank you, and sorry for the inconvenience.

Hi I have got a followup. It will actually be very hard to fix. Please try to use the Shrinkage compensation in Filaments -> Advanced.

Thanks for the feedback! I'll give that a shot next time I need to do something similar, and hope for the best for an eventual solution. Cheers!

Idle musing: I imagine that painted elements are literally painted on the model's original surface, and that XY Compensation grows the outer shell "beyond the paint." If so, perhaps XY Compensation could be modeled/visualized in the editor view, and then painted elements could be applied to that?

Hi, your assumptions are correct and it is sadly easier said than done :smiling_face_with_tear:
