Comment 88 for bug 745608

Some additional information (although I'm not sure how comforting it's going to be):

Ubuntu 10.10 also exhibits the same behaviour (but only after I switched from compiz to metacity) and has the following packages:
xorg 1:7.5+6ubuntu3
xserver-xorg-video-intel 2:2.12.0-1ubuntu5
linux-image 2.6.35.28.36

My Ubuntu 10.04 setup with a 2.6.38 kernel does not show the problem with the following packages:
xorg 1:7.5+5ubuntu1
xserver-xorg-video-intel 2:2.9.1-3ubuntu5
