Dear all,
  I tried the sample program "mvarray.c" of OpenGL Programming Guide (red-book) with Mesa3D 7.6.1 but the result showed only the last line stripe regardless of how many line stripes to draw. (I copy Mesa's OPENGL32.DLL to my binary program directory to use Mesa instead of hardware driver)
The result of my hardware driver is right.
 
Thank you,
