Waylander,
I'm using Calibre and Yosemite but I'm not having this resolution problem.
I would try completely uninstalling calibre by using a 3rd party tool such as AppZapper, then re-installing it. This will reset all your Calibre settings, but it's the next thing to try.
BTW - I was having a bug of my own: the preferences dialog is opening full screen, then, when I close the dialog, the full screen display remains open as a blank screen. Removing the app and reinstalling from scratch solved the problem.
