It appears to be a bug in xserver-xorg-video-intel that occurs
under kernels 2.6.38 and 2.6.39. The latter seems to help some --
in my case anyway -- but the problem is still there. See bug
622308 (which has been closed); bugs 626337 and 627249 are similar.
(I'm running an Asus laptop with an Intel 965GM chipset.)
