What do you find if you disable compositing to get Xfce to start, and
then enable it once xfwm4 is running successfully? I find that seems to
work. So it fails some sort of initial probing, but then is able to
activate the feature later, anyway. (As if there are two different code
paths for this, or something is getting corrupted in memory during
start up, but that isn't happening later on. I haven't had a chance to
look at it in gdb again, yet.)

Yes, I've found the same thing. I was confused when video streaming
suddenly stopped working for me, and then I saw Firefox was logging that
it had "exhaused GL driver options", for a site that worked a month or
so ago. (I imagine 9-BETA may still work, but I don't have anything
running it at present.)
