Why are my pdf pages temporarily blurry in Preview?

I am using Preview to display a 1MB pdf file that contains a presentation. OS X High Sierra.

At each page/slide, the image is blurry for about one second, before it gets sharp (correct). I have found this discussion about this problem.

I do not understand this unusual behaviour. If it were a very big pdf file, I would understand that it takes time to display everything correctly.

Is there a solution? If not, what is an easy and free alternative to Preview that allows me to display my presentation without waiting for the blur to disappear?


Solution 1:

This is a soft solution, I load the pdf file with chrome, them command+shift+f, press left and right arrow for slide alteration.

I hope this helps.

Solution 2:

Please have a look a this thread which provide useful information

As a summary : you can use alternative viewers such as Presentation.app or pdfpc

They are available via Homebrew

  • brew cask install presentation
  • brew install pdfpc
