I produce a lot of pdf files using LaTeX and thus, I also read a lot of such files. After the update to OS X 10.10 the fonts are not smooth anymore. However, Safari seems to handle it much better than Skim (see screenshot for comparison).

The option "Use LCD font smoothing when available" is enabled; without it, the texts are almost unreadable. Anyone has any clue how to make the font looking better?

Hardware: I use non-retina MacBook Pro 2011 + Fujitsu 27" LCD attached with dual-head DVI.

    This is happening with non-Retina displays in general (including mine). There's a thread in the Skim users mailing list where the developer says that this is a PDFKit bug and he can't do anything about it.

    Thanks dfan. Could you - Alex Pigeon - remove your edits, so that people can see the screenshots in full size?

This bug appears to be fixed in 10.10.3.

I can confirm (with Pixie) the rendering is the same in Preview, Skim, and QuickLook, at least with subpixel rendering forced to 2.
