Thank you very much for your reply.

I ran the program with the following setting. Here are their results.
Widget_draw graphic_level = 2

Original setting: Renderer by default and retain = 2 Slow
Renderer = 0; Retain = 2 Slow
Renderer = 1; Retain = 2 Slow
Renderer = 0; Retain = 1 faster(at least 4 times faster than case in
retain=2)
Renderer = 1; Retain = 1 faster(at least 4 times faster than case in
retain=2)
Renderer = 0; Retain = 0 fastest(a little bit better than cases in
retain=1)
Renderer = 1; Retain = 0 fastest(a little bit better than cases in
retain=1)

I will check the speed of windows version, my XFree version, and my
video card type and come back to you later.

Sam
