And it still fails?

There is certainly some value in having the "respected gurus of the
community" see the problems "mere mortals" have when trying to use
these things :)

I remember it took me quite some time to figure out these details as
well.  Much of it is documented, but not always where you would be
looking.  And not always clearly pointing out how badly things can
fail if you ignore that "little, insignificant detail".  The
requirement of having a valid colormap in XCreateWindow took me quite
some time to figure out.

Of course, the current attitude seems to be that Xlib (and xcb) should
not be used, except by toolkit authors.  The rest of us should just
use the standard toolkits.  (Now, if someone would actually come up
with a toolkit that didn't suck, that would be marvellous.)

That's the strategy I've had the most success with, yes.
Unfortunately, I can't think of an obvious, simple one right now.
