Comment (by glynn):

 Replying to [comment:8 msieczka]:

 Nothing out of the ordinary there.

 The context, Pixmap and GLXPixmap are all being created with respect to
 the same XVisualInfo* value.

 The GLXPixmap case works fine on Cygwin's XWin.exe, X.org with "nv"
 driver, and X.org with "nvidia" driver (the first two with X.org's libGL,
 the last with nVidia's). This is with X.org 7.2 & server 1.3.0.0.

 This is looking like an issue with the Radeon driver.

 Note that we handle the case where the server fails to create the
 GLXPixmap. The problem is that it creates the GLXPixmap then complains
 when you try to use it.

 One finale check: can you try "export LIBGL_DEBUG=verbose" before running
 it, and see if that sheds any light?
