Details:

I just upgrade to Ubuntu 6.10 
and GNUstep does not draw properly with art backend.
All the windows are empty (not draw).
xlib backend seems to be fine.
If I turn off XWindowBufferUseXShm and turn on XSync(),
I can track it down to XPutImage() in XWindowBuffer.m.
(request code 72 is from XPutImage()).
Here is an error output I got (I also dump the parameters for XPutImage):

2006-10-26 21:20:14.499 Typewriter[15221] XPutImage, 37748741 270463712
270505376 (0 0 64 64)
2006-10-26 21:20:14.499 Typewriter[15221] X-Windows error - BadMatch (invalid
parameter attributes)
          on display: :0.0
                type: 0
       serial number: 623
        request code: 72

One of the parameter for XPutImage is wrong.
x, y, w, h seems right.
Therefore, drawable, gc or ximage can be wrong.
I suspect ximage is the reason.

That is pretty much all I can track down.
