I did it the other way.

xlib works fine for me too, art used to work, cairo is broken, but it 
is not "inverted" it has a strange color permutation. (everything is 
bluish)

Ideally, they should all work. Xlib is by way faster (if you think it 
is smarter, it doesn';t just shovel bitmaps over the network but, for 
example, uses the server to display the fonts) especially if you use 
fonts with bitmaps and not AA. Then Menus look like local. Scrolling 
is slow though.

just as a test I did here

x86->ppc with art and the corruption is strange: some elements adre 
correct in color, some nots (blue cast). But for example clicking on 
the scrollers makes them alternatively display in the correct or in 
the wrong color, while test in the menus displays black and gets blue 
when clicking on it...

I'm almost sure it used to work.... years ago.
