Yes I think Mesa switched to SGI GLU

OK got polygon.shp on gvtest & openev

No jitter problem on my side! 

OK maybe don't understand your problem!
When you say 'jitter' you mean:

     To make small quick jumpy movements. 
     The pictures on the wall jitter 
     whenever a truck drives by. 

When I scroll it does redraw but it look smooth
to me!

I'm scrolling Up/Dwn/Lft/Rht at 477416.00E 4761146.00N
The poly fill the window. The window is the default
size when starting openev.py.

Does the jitter occur every where or only on 
specific poly?


Again I'm using xfree 4.2.1 and Mesa is inside XFree

XFree86 Version 4.2.1 / X Window System
(protocol Version 11, revision 0, vendor release 6600)
Build Operating System: Linux 2.4.19 i686 [ELF] 


My GLU is:

$ ldd gvtest |fgrep GLU
        libGLU.so.1 => /usr/X11R6/lib/libGLU.so.1
(0x4031f000)

$ls -l /usr/X11R6/lib/libGLU.so.1
lrwxrwxrwx    1 root     root           13 2002-11-06
22:51 /usr/X11R6/lib/libGLU.so.1 -> libGLU.so.1.3
$ls -l /usr/X11R6/lib/libGLU.so.1.3
-rw-r--r--    1 root     root       507672 2002-10-16
16:16 /usr/X11R6/lib/libGLU.so.1.3


Anyway I still have prob. with line coming and
going from no where when scrolling.


I'll let you know is I find anything
