    Thanks a lot. I'll probably will need to draw a chart, using everything that I read here..

    In this model, 2D and video acceleration went through the X server, the X driver, and the DRM driver, while 3D acceleration went directly to Mesa and then the DRM driver.
    Sorry, does it mean that Direct 3D calls are not used, when playing Videos, and it's closer to 2D in the way how it's performing? Why it flickers in Compiz, just like any other 3D app, then?

    I mean.. Is there a chance that the Video would be played in with Desktop Effects enabled _before_ DRI2 implementation?


    By the way: were there any considerations about having some sort of "X Windows system: Desktop edition" - without Network transparency requirements or so (I mean, free of "Client-server" model).

    the flicker is not generally caused by 3D apps, but by conflicting accesses to the framebuffer, like when 3D directly renders to framebuffer.

    But it is also possible to render Videos directly to framebuffer, which is how the Xv Overlay works.

    it should already play fine with desktop effects enabled, if you use textured video.

    you have probably configure it using "gstreamer-properties".

    this does not make sense.

    Wow! Mesa 7.1 officially released. This is surely a sign of the Apocalypse. The next thing you know, The Four Horsemen will show up (I'm going to offer them a beer).

    This is a good read (summarizes the different aspects of X rendering):
