I just quit the dock and restarted it with 'cairo-dock -c.' I also changed the theme (neon) and removed LibreOffice from the dock. So far, so good. I'm thinking, though probably a stretch of the imagination, that it may be possible that after using LibreOffice, there is a process from it still running. I have the extension from LibreOffice also installed into Firefox. I'm thinking that LibreOffice (soffice.bin) made what ever GTK needs to work crash, resulting in Cairo-Dock being invisible, but still right-clickable. In other words, it seems like something has to crash before the dock will become invisible, and I'm thinking what ever it is has to be GTK-based. It's happened about five or six times so far. But, I have recently reinstalled Xubuntu 14.04 because my previous version was an upgrade from 13.10 to 14.04. I'm never doing that again. New number, new install. It even got to the point that my macbook was randomly disconnecting itself from my monitor. Before, I thought it was getting too hot and turning itself off but found out otherwise when audio was still coming from my headphones. I also can't run Chromium (see screenshot attached; the dock in the screenshot isn't cairo, it's another panel placed on the bottom) without having to move my mouse over the whole area for the page to render. Several problems have not surfaced again because of this, but the Cairo-Dock issue still happens every now and then. I think my OpenGL version is 2.1. Also, I've noticed that if I select to use my laptop's output, rather than just the monitor's, the dock places itself relative to where it would be at my laptops resolution. As a matter of fact, two default backgrounds load on top of each other every time I log in to my computer before it corrects itself to the one I chose. I'll just have to wait for a crash and see if the dock becomes invisible to see what's happening and then try to remember to save a copy of the crash report of what ever it is to send you.
