Comment 30 for bug 111257

I can confirm this behaviour too; it only happens when compiz is running. It happens with even just a tiny crappy mobile phone video, so it's not related to hd output. If I kill compiz with 'metacity --replace' running the same video then works.

This is with compiz 0.5.0 and the Debian 2.0.0 xserver-xorg-video-intel package on an 915GM/GMS/910GML. I have a very un-fancy xorg.conf with

Section "Device"
        Identifier "Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller"
        Driver "intel"
        BusID "PCI:0:2:0"
        Option "UseFBDev" "true"
        Option "XAANoOffscreenPixmaps" "true"
        Option "DRI" "true"
EndSection

Section "Extensions"
        Option "Composite" "true"
EndSection

Also seems to be reported by ubuntians
