I had come into this problem in the past after upgrading libgl1-mesa but i am not really sure if that was the problem.
Please let me know if i can provide more information than the list of the packages and the specifications above.

After upgrade to Kubuntu 13.10 there was a pure crash in kwin which finally led in finding the source of the bug and solving it.
Related descussion about kwin crash created by this:

https://bugs.kde.org/show_bug.cgi?id=326321

The problem is created by loading the wrong libGL.so.1 in a system with bumblebee and dual graphics cards (Intel HD 3000 and nvidia NVS 4200M). When this version of libGL.so.1 => /usr/lib/nvidia-304/libGL.so.1 (detected using ldd `which kwin`| grep libGL) is used as primary it creates this problem in the graphics which in later version leads to a kwin crash or restricts compositing to XRenderer. For more information and debugging trace please read the above link.

How to reproduce the bug:
In an optimus capable laptop loading kwin with /usr/lib/nvidia-3**/libGL.so.1 instead of the mesa should show a similar screen in Kubuntu 13.04 or even crash in a later distribution (13.10). /* ln -s /usr/lib/nvidia-3**/libGL.so.1 /usr/lib/libGL.so.1 */

Solution:
Create a link for libGL.so.1 pointing to /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1 instead of the nvidia path (and similar for lib32). Tested only in Kubuntu 13.10 under 304, 313, 319 version of nvidia driver.
