High Sierra 10.13.1 Blurry Preview in Preview

I am having a problem with Preview app in High Sierra 10.13.1. The preview in preview became noticably and irritatingly blurry after my upgrade from Sierra to High Sierra. I am attaching the comparison between the rendering in Google Chrome and Preview below:

This is such a dealbreaker, since I use my Mac mostly for reading pdfs and other academic purposes. I would like to solve this without reverting to Sierra. I would appreciate any tips or solutions.

Thanks.

MacBook Air (13-inch, Early 2015), macOS High Sierra (10.13.1), null

It is best illustrated, when you drag the screenshots to a separate tab in your browser and compare.

If I do that the two images render at slightly different sizes.

The distinction is definitely there. I will back this up with screenshots of identical resolution. However, the solution lies in blocking some other application. I will report the developments.

FWIW. I would suggest trying Adobe Acrobat Reader DC 2018 and see how you like the results.

I would mention neither is "blurry". Preview renders characters with slightly more "weight". When one is in Safe Mode accelerated graphics is disabled. That may account for the difference.

Is there any way I can tune that? For instance, prevent accelerated graphics from meddling in Preview's affairs?

Only by staying in Safe Mode.

Which I cannot do, because it makes the rest of the experience abysmal. The readability of Preview is objectively worse, I believe. I hope that this is resolved as soon as possible.

Yes, I gotta admit that they look the same. Could you, please, find two pdfs that have black text on white page (usual articles)? The difference looks sharper in these types of examples.

As I just mentioned…

So at this point I'm thinking it may have to do with what fonts are being used and which PDF standard.

FWIW, there is a slight difference in the "weight" of the characters with certain PDFs.
