I’m having this same issue. I was previously working in Lectora 11.3.2 and recently upgraded to Lectora 17. I opened a project built in Lectora 11 and noticed the text in all of my buttons was very blurry on preview and publish and in the LMS. It’s not only the buttons, all the images are also fuzzy. This same project looks great in Lectora 11. I contacted Lectora Support in December and they have not been helpful and now completely unresponsive. Has anyone found a fix to this issue? This is causing a real problem to my project.
