Okay, I think I see the problem. It looks for a visual which

1. Has depth and stencil bits.
2. Has a corresponding picture format with alpha bits.

1. is satisfied by many visuals, but 2. is only satisfied by the depth 32
visual, which probably doesn't have stencil bits. It may be possible to fix
this with yet another rework of the xserver GLX visual code, but in the
meantime could cairo-dock work without a stencil buffer?
