libGL warning: 3D driver claims to not support visual 0x4c
Nbr of joysticks: 0

The program 'desmume' received an X Window System error.
This probably reflects a bug in the program.
The error was 'GLXBadContext'.
  (Details: serial 422 error_code 155 request_code 144 minor_code 5)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)


According to the forum, it happens on intel cards, I have an r300 and get the same error. I'm using latest git of xorg, mesa, drm and xf86-video-ati
