Comment 6 for bug 861268

The plot thickens... I just noticed that when I see the problem, clicking the terminals title bar and moving the terminal restores the images. Hence, it can't be terminfo. Finger is now pointing at X11/compiz/unity.

I'm running Unity 3D with the propriatary nvidia drivers (yeah, I know... :-) :

$ lspci | grep -i nvidia
01:00.0 VGA compatible controller: nVidia Corporation GT218 [NVS 3100M] (rev a2)
01:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1)
$ dpkg -l | grep nvidia
ii nvidia-common 1:0.2.35 Find obsolete NVIDIA drivers
ii nvidia-current 280.13-0ubuntu5 NVIDIA binary Xorg driver, kernel module and VDPAU library
