Comment (by hcho):

 Maybe try size=100,100 and see what the output size is.

 Not sure what it is, but you can also try to directly draw to the front
 buffer without buffer swapping
 1. Change line 223 in lib/nviz/draw.c to {{{GS_set_draw(GSD_FRONT);}}}
 2. Comment out line 480 {{{glXSwapBuffers}}} from lib/ogsf/gsd_prim.c.
