If you look at the glxinfo.txt attachment you can see the full output of glxinfo and see that compiz is quite right, you lack proper support for the GLX_EXT_texture_from_pixmap and are using the Software Rasterizer (check the renderer string). I don't know if this is a configuration issue on your system or a bug in the driver so I've reassigned to the radeon driver. Please run `apport-collect 686164` to collect any additional data needed for a complete report for the driver.
