I suspect that if your system is running Unity with LLVMpipe then maybe we're re-exporting that to applications like games when we shouldn't. Please run:
    env | grep LIBGL
and let us know what the output is.

To confirm the root cause of the problem, please also:
    1. Install package mesa-utils
    2. Run: glxinfo | grep OpenGL
And paste the output into this bug.
