It seems to apply to Apple and MN engine as well. The only difference MN has the issue when zooming out of a bigger size, not the other way around. On this, I could be just imagining things.
The main issue is that the blurriness is visible on both PDFs and excerpts. A couple of screenshots show that zoomed PDFs in a middle range appear to be blurry, while excerpts are blurry when getting / being smaller.
PS: iPad doesn’t appear to have the same issue.
Hello
Thank you for your screenshots, we have been focusing on this issue, these are similar discussions on the Marginote Chinese forum some time ago ：
https://bbs.marginnote.cn/t/topic/4873https://bbs.marginnote.cn/t/topic/10045https://bbs.marginnote.cn/t/topic/11239https://bbs.marginnote.cn/t/topic/5839/2https://bbs.marginnote.cn/t/topic/5706
We are still working on them. If you find any other new leads that may be causing this problem, please let us know.

The other post is from August and this from Dezember. I hope you are getting close to the issue.
Question: Can I request a new EDU code later if I do not buy it now? 48hrs are over anyway.
Sry, cannot try anything for real yet, it would just blur my eyes and hurt. 
Hello
Yeah, if you haven’t used the code, you could apply for a new one. Note that one student could only purchase with education discount once. Sorry for the late reply ~
