Composite internally, which is always available, so we just
blindly
ignore the config setting and give you backing store if you
ask for it.
There may be bugs, I freely admit, but it's definitely meant
to work.
If it doesn't it's probably a bug in X and I'll fix it, so
hook me up
with test packages and I'll take a look.
I've uploaded an x86_64 rpm here [1], the srpm is here [2].

I compiled the RPM from your source on F19/x86_64 with an Xeon
E3-1200 v2/3rd Gen using the intel driver (Ivybridge GT2). As ajax
was saying, the window exposes work just fine: I can raise other
windows on top of xfoil and when I re-expose xfoil it redraws
properly.
You likely have a compositing window manager running? Cause it
definitely did not work with kwin with compositing turned off.
Anyway, ajax has posted patches for this to the xorg-devel list [1].
And btw, I've now posted a review request for xfoil [2] with a
polished srpm, in case you are interested.
