Summary
Currently opengl apps do not work correctly when composite is running. This is a BIG bug and annoyance for desktop users, especially as composite-by-default is set to be included for gutsy. This should be fixed via redirected direct rendering. It is especially important as modern applications use opengl interfaces, such as blender and google earth, but also for smaller opengl parts, such as the visualisations in amarok.
Rationale
Users of ubuntu, both advanced users and novices, find it annoying to have to disable the compositioning window manager whenever they want to run an opengl accelerated application. Solving this requires deep changes to the structure of the X server and the display drivers, and is a future plan for the Xorg devs: http://dri.freedesktop.org/wiki/DirectRenderingToRedirectedWindows (A prototype for this has been developed by Kristian Hogsberg: http://hoegsberg.blogspot.com/2007/08/redirected-direct-rendering.html). However, it is a big job, so I believe that the Ubuntu devs should help out.
I'm sure many people know more about this than me, so feel free to add details.
