I have a strange problem. In the resulting PDF of when my large (200+ pages)
classicthesis.sty project is compiled, it works just nice, except that the part introductions are invisible. The text is there, it can be selected (tried both Okular and Acroread) and copied, but not viewed. It is invisible, or in the same color as the background.
I see that a similar question was asked here: Problem with includepdf invisible text in document and I have the same problems with providing a MWE. Right now I have no idea what part of my enormous document actually causes this error, and am looking more for possible sources or ways to debug this further, so I can show the relevant parts of code that causes it.
My assumption was that there were some commonalities between problems causing text in the resulting pdf to be invisible, i.e., selectable.
Update 20150925; I have now resolved the issues by updating to the newest classicthesis.sty file (2015/01/01 as of now). Then the problem disappeared. Before I commented absolutely everything out, but the problem persisted. I did not proceed to research what in the difference between the sty files made the improvement.
