How can I make PDF forms filled in Preview show correctly in Acrobat?

Dears list members, there is a known issue with PDF forms filled in Preview: the fields do not show properly in Adobe Acrobat. How can this issue be solved? On the internet, I found two basic solutions: (a) to flatten the document by printing it as a PDF and (b) to use a costum-made script. Is there an official correction for this bug that does not involve installing suspicious scripts? Thanks!
