Just run a compositing manager on Xephyr and make any window
translucent. As soon as it stops being fully opaque, it becomes
invisible (except for some small, seemingly random areas, sometimes),
you only see the shadow behind it. So the global alpha value of the
window doesn't seem to be handled correctly.

If you can't reproduce it, I can create screenshots tomorrow at work.
