This bug occurs even when just playing a video with VLC. It seems to occur only when multiple displays are attached and only in some configurations. In particular non-clone configurations seem to be affected. The workaround that helped me was

Option "AccelMethod" "uxa"

in the "Device" section of xorg.conf.
