Same thing happens under vtwm, when a root window image is set with
using xv.  Root window becomes smooth solid grey50 when xcompmgr (v1.1.1)
is started.  Talking about Xorg-6.8.1 cvs Dec 24 10:38 MET.
Does not happen when root window is set using redhat's xsri tool.
Hardware: nvidia geforce4, drivers 6111, 6629.  This is with RendelAccel disabled.

With RenderAccel enabled, root window basically becomes some messy random
pattern.

Here's an overview of some tests I did:

General notes that apply to all tests
=====================================
- nvidia_drv is version 6629
- xsri and xv: tiling the root background starts at (0,0), not at the center of
screen
- display: virtual 2000x1600
- in subsection Extensions: both Composite and RENDER enabled (xcompmgr needs
them both enabled)
- in subsection Display:
  Modes		"1024x768" "1280x1024"
  ViewPort	0 0
  Virtual	2000 1600
- (II) NVIDIA(0): Setting mode "1024x768"
- xcompmgr -f -D 8 -I 0.025 -O 0.025 -l -5 -t -5 -c -r 8
- messed up means: some random pixel-mix like pattern
- in Tests I and II, vtwm always unresponsive after killing xterms/windows; this
also
  affects keyboard; keyboard seems to be in messed up state such that for instance
  keypad left/right arrows now perform ctrl-left/right action in editor joe;
iconifying
  a window by clicking on the titlebar button always keeps working though...;
  de-iconifying does not work anymore though.  After switching to VT and back to
Xserver,
  the keyboard and mouse are sane again, and e.g. vtwm menu popups also work again;
  everything ok except of course messy background.  Background is always restored to
  good original state after exiting xcompmgr.

Tests I:
========
- RenderAccel + nvidia_drv in otherwise standard xorg.conf

notes:
- exit of xcompmgr: xv background pattern reset correctly

Tests II:
========
- RenderAccel disabled + nvidia_drv in otherwise standard xorg.conf (horribly slow)
