Same issue here. Just normal flat (some transparent) buttons, no dropshadows, no gradients or other fancy stuff. But the text becomes VERY fuzzy after publishing! Same for shapes with text. Font is Calibri and/or Calibri Light, and everything looks fine until I publish. That may be the most annoying part, that I have to redo almost all my buttons and shapes!
I’ve added a small screenshot with a normal textbox and a shape with text. The textbuttons are just as fuzzy. I hope this can be resolved because I love using transparent buttons in my menu’s, but not when they look this horrible 🙁
Edit: The screenshot does not really do justice to the MASSIVE difference in crispness.. but the text is supposed to be the same color dark blue.
