I also see something like this when I zoom into a pdf, any pdf that recently displayed perfectly. Both in regular view and in full screen view. In my case it takes up about 5-40% of the display depending on zoom level and looks a bit like like vertical margin gone haywire.
I updated to Mavericks 10.9.1 today so that may be related. I'll try and downgrade Skim.
