Yes, I'm running xcompmgr; alpha transparency is working fine in other
applications.

I've noticed a peculiar detail--this problem does not occur when
running X without a window manager, say if I only run xcompmgr and
emacs in my X session. I've tried this with multiple window managers,
so it doesn't seem to be the fault of either one.

For now I'm back to running Emacs 23.3.1.
