AI files open in latest Designer (or beta) create unsightly joins/lines

[abarkalo]

Very often I cannot open an AI file in Designer because there are lot of hair thin lines that form where the layers are joined. If I open the file in Illustrator I don't see these lines. Also if I export to PNG from Illustrator then this problem is solved - but then I have a raster layer.

This problem persists even if I create a PDF file in Illustrator and place in Publisher. The interpretation of curves leaves these unsightly lines.

I go through the layers in Designer to see what must be causing this but I can't see the issues.  About the only thing I can do is painstakingly move the vector paths around in certain layers - but this would literary take me hours for super complex files.

Please see attached. This is from a bearded man graphic - see the line around the mustache.
