Comment 78 for bug 278318

Proposed packages works for me fine too but I don't know why Textured should be the default?
The only problem of Overlay afaik is that if you use special Compiz effects they doesn't work in this field. I mean who cares? Glxgears and nearly no other OpenGl app work fine with Compiz so why should the video output? With Textured there is a higher cpu usage and the tearing which is of course not as severe as the vsync tearing but still makes movie watching very annoying.

Afaik Ubuntu is for the standard user who doesn't want to change many options to get the best experience. Textured video is something for power users who want special effects even on videos who are also able to set an xorg.conf option.
I mean most people watch videos in full screen so there is no need for eye candy effects.
