I think I got it now.
There are six text regions on my screen that are dynamically changing just about every second.
For each of these six items I a window update by modifying the ofscreen pixmap and then do a 
GrCopyArea. Because they occur back to back the screen is rewritten atleast that fast and When
these text areas are rewritten the server do back to back GsPreparedrawing, FillRect which calls
drawhorizline. This sort of behaviour seem to be problematic for nanoX and I'm nor sure how to
get around it. It's like these tasks are not sync properly as it seem that I'm writing one ontop
of the other.
Gregg, does this seem plausible?

thanks
Jr.
