We have filed a similar bug report some time ago directly with Mr. Marcin just for the M200+ but in recent Z-Suite this bug shows also on M200 printers. Since that report the quality visibly improved.
The problem is that a few of the top layers (3-5) of every shape has larger dimensions than the layers underneath. I have attached a few photos that illustrate the issue.
This happens regardless of the material type or settings, layer height, etc.
