	It works just fine when I move around a window only over the
desktop/root-window. I'll attach another screencast showing that, if you
want.

	That's another odd observation. compiz does not report about a missing
stencil-buffer on my system (GeForce7900GT, 1.0-9755 driver). All errors
I get at startup-time are these:

  compiz: Failed to load slide: freedesktop
  compiz: video: no 8 bit GLX pixmap format, disabling YV12 image format

Best regards...
