No ideas, but I see bazillions of them as well, not using KDE, but am running intel graphics.
Thanks for the pointer, Tom. I was KDE with Nvidia graphics before, so was already looking suspiciously at the Intel driver (which is why I mentioned it originally). I've also managed to find an entry in one of the older bug reports (from 2009) that sheds some light on this:
"Those files are where your pixmaps and other graphics objects are stored. They do not consume fds, but they are open files. We have longer lifetimes on these objects than we should, but there shouldn't be any actual leaks -- you'll reach a steady state at some point."

So it looks like it's possibly just normal operating practice for the Intel driver, albeit somewhat messy for tools like lsof.
