Hello

I want to test the demo glsync (...\progs\xdemos\glsync.c) with the option -s b to use the verticale sync.
The problem is when the function glXSwapBuffer calls the function GetGLXDRIDrawable(dpy, drawable, NULL), GetGLXDRIDrawable returns a pointer(pdraw) which is NULL.

pdraw is NULL because psc->drawHash is NULL.

The function __glXInitialize(dpy) called from GetGLXDRIDrawable returns a display private wich already exists

I want to know why the drawHash structure is NULL and how to do to have a drawHash which is not NULL ?

Thanks
Nicolas Cadio
