This is the same PDF
a) in the Viewer app (Mac OS X)
b) in the CT PDF Viewer
I assume this has something to do with embedded types and/or encoding. No problem to display the file in Skim.
The viewer behaves quite sluggish when handling this file (8 MB, CT has 4 GB).
I do not use the PDF viewer so often, but nowadays I would try to print the PDF as PDF (Bullzip Printer App under Windows, from the Viewer app under Mac) to get another, perhaps (for CT) properly coded PDF file.
The PDF viewer is an external PDF library suitable for displaying relatively simple PDF documents. In the future, it may be either removed or replaced with some alternative Java PDF viewer.
