This is a problem is 6.8.1 as well. I have a dual head setup that uses two seperate nvidia video cards (an agp and pci). When I have xinerama enabled and attempt to make drop shadows with xcompmgr, everything on the screen dissapears and is replaced with their drop shadows. Also the other screen is just one big shadow regardless of what I have on that screen. However, when xinerama is off and I still use two screens, the drop shadow support works just fine on both screens. This could be an issue with my drivers or perhaps an issue with seperate video cards setup as a dual-head system. Otherwise, thanks for a great release, I'm glad to see improvment and imigination in this product.
Whats the status of this bug when you use a current xorg release?
Im not sure. I've replaced my dual card setup with a single nvidia card running twinview. I've not had any problems with my current setup.
I'm closing the bug as there are no hardware to test this on.

I've been experiencing this bug every time I've tested composite the past few years. The result has always been as described. Drop down shadows are drawn above the windows. Some programs like gkrellm sometimes manages to draw above it's shadow causing it to flicker. Right now I'm using xorg-server-1.3.0.0 with a single GeForce 6600 LE in xinerama mode. This is one of those Xinerama + Composite issue and it might be a low priority thing but composite will soon be inevitable on the desktop and I don't want to sacrifice dualhead.
Created attachment 13687 [details] nvidia bug-report could also be useful
i have the same setup with the same behavior. what i wanted to add is, that there are workarounds: - nvidia: use twin view. problem here is that twinview can only rotate both screens or none. - intel/radeon: i read about a mergedfb mode, which also allows to use composite with something near to xinerama.
Are you still having these problems with recent deliverables? Please try xorg-server-1.11.1
This should be fixed in xserver 1.15, the Composite code got a bunch of Xinerama-related fixes there.
