Well, yes, but it ought to work regardless of the xorg.conf setting,

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.
