Bug Description
Binary package hint: compiz-core
I am using gnome. I have a dual-head setup, using the nvidia TwinView feature to expand my X onto my two displays (one being 1680x1050 and the other 1280x1024).
When I enable the desktop effects, my desktop wallpaper and icons disappear. The desktop background turns black. The rest of the visual effects seem to work fine. If I switch the effects off, I see the original desktop wallpaper and icons again.
I am using a Nvidia GeForce 8400 video card, using the "nvidia-glx-new" package version 100.14.
See attachments for various logs and my x.org configuration file.

I'm not sure if this will help, but I did find this interesting:
1. Turn off desktop effects (background wallpaper and icons appear)
2. Run gnome-terminal. Edit the current profile and give it a transparent background. Verify that you see the background.
3. Leave gnome-terminal running, then turn on desktop effects. gnome-terminal continues to show the background.
4. Move the gnome-terminal window around the desktop. gnome-terminal continues to show the "correct" background (i.e. the background portion that it shows changes to reflect what is really "behind" the window).
