Public bug reported:

Binary package hint: libgl1-mesa

Intrepid, latest mesa (7.1~rc3-1ubuntu2) on an Intel i945:

Many games, such as Neverball/putt and Emilia Pinball, run seemingly
fine on a base Intrepid install without any desktop effects enabled.
However, when Compiz or any other OpenGL application is launched overtop
of these applications, they exhibit strange texture corruption. Some
textures cannot be identified, while others look like they were swapped
around.

Briefly, for about 1/2 second, textures look fine on first load.

Attached are some screenshots showing the problem. Neither game outputs
any new errors to the terminal when corruption occurs, with the
exception of "Failed to initialize TTM buffer manager.  Falling back to
classic." which also appears without compositing enabled.
