Hi, in order to help you we need more information, such as the version of Adobe XD you are using and the features of your computer?
Version: 220.127.116.11 x64 I actually noticed even on other artboards when I export as png at 3x the image isn't really clear
Thank you for your answer. Does this problem also occur with other files?
Yes, it does but at the moment I'm concerned about the pdf how do I fix this?
...... a few months later
I have not experienced that issue before and just tested this (on my Mac) and it works fine. What app are you viewing the PDF in by the way?
