Sure Lars, I was going to do it anyway because of other issues with pdf-tools.

It indeed fixes part of the problem:

* LaTeX previews in org-mode are high resolution now.
* Also adds the frame-scale-factor function that’s used by the fix to pdf-tools [1] blurry rendering.

But other related issues remain:

* doc-view still renders low-resolution svg.
* doc-view still renders low-resolution pdf (which is not the topic of this issue but may be relevant).

Best regards,
Carlos
