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: 18.104.22.168 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?
