Screenshot (black terminal window)

I have an Ubuntu 14.10 system and a Intel DQ35JO motherboard with and
integrated video chipset. I'm using the UXA backend because of another
(unrelated?) problem with the default SNA backend. After some hours of use new
windows become completely black, and I'm forced to blindly close all programs
and log out of the system. xserver-xorg-video-intel current version is
2.99.914-1.

P.S. I'm waiting for the release of a version of Intel Graphics Installer that
I can install on my Ubuntu 14.10 system, for testing.
