Nope, I don't have such an entry in /etc/X11/xorg.conf. There even
is no Extensions section! However, I can run Xnest like this:

 Xnest :10 -extension Composite -query localhost

which switches Composite off, but I think it's already off.
As expected, this does not make any difference to resizing the

When I use "+extension Composite", Xnest coredumps immediately.
