Different line spacing OTF fonts

I've noticed that texts in projects made on a Windows machine have a different line spacing or vertical positioning when I open the same FLA on a Mac. I always use OTF fonts so that should make no difference whether I'm using Mac or Windows? When I've made a FLA on a Windows machine and open it on a Mac later mostly all texts are shifted up and the text lines are much closer together. I then have to make the line spacing bigger and move the texts down a bit. This button for example has text that is vertically centered when created in Windows, but when I open that same project on a Mac the texts is positioned higher.

This is no problem with Photoshop or Illustrator. Only Animate doesn't seem to handle OTF fonts from Windows to Mac and vice versa. Why is this??
