OpenGL implementation is from nvidia-drivers-260.19.36, so most
probably others have the same problem. However there are probably not
that many people using a quadro board with stereo enabled X server.
Configuration may also be a matter. Perhaps it?s best to use an alpha
visual when available but fall back to a non alpha one and print a
warning if it is not available .

- From reading the code, the original version seemed correct to me, so
It is strange that things worked by disabling the context check on my
box. I?ll try out to use the newer OpenAL version. I currently use
openal-1.11.753. With bino-0.8.1 I did not have the problem, but this
does not mean anything since the audio code massively changed since then.
