Got it.  That's a "DesktopDoubleBuffered" registry value from a default X11Drv
config key.  If I set it to 'Y', exception disappears.

Reversing patch [1] helps me too.  If I change code this way:

     }
     if (!screen_depth) screen_depth = DefaultDepthOfScreen( screen );
 
     /* If OpenGL is available, change the default visual, etc as necessary */
-    if (desktop_dbl_buf && (desktop_vi = X11DRV_setup_opengl_visual( display )))
+    if ((desktop_vi = X11DRV_setup_opengl_visual( display )))
     {
         visual       = desktop_vi->visual;
         screen       = ScreenOfDisplay(display, desktop_vi->screen);
         screen_depth = desktop_vi->depth;
     }

exception is gone too.  Something is getting not initialized in the file or
initialized at wrong time, I guess.
