@Annsnrzk, I also have blurriness, but I've seen it before and know a workaround: you are most likely using Chrome, go open the same page in Firefox and the blurriness is gone.
Browsers do not always execute web pages the same way or even according to exact standard, so they have differences. I don't know what in Chrome causes this and in which devices or OS's it occurrs, if anyone knows what triggers it and when please let me know, I also have professional curiosity on this issue 😉.
