Hm, yeah that's also what I believe. I am observing lots of crashs of application (its pretty much an instability nightmare ATM). The crashs seems to be pretty random... e.g. ATM i am trying to reproduce the kwrite issue and it is gone. I didn't find a system behind it so far. But all the crashs seems to be related to XCB. It happens also with krunner quite often while typing something. I am currently running "OpenGL 2" with NVIDIA prop. So I don't think it is related to Mesa. I will give XRender next time a try, but run into some issues while starting KDE a while ago.
