Thanks Anders,

I didn't realize another assault on this bug was taking place on the
compiz side.

I have installed your package, and now about a week later, I can confirm I
don't see any refresh artifacts. Not the way they were, at any rate.

But the whole thing has become unstable, and because of the way I
installed compiz-fusion-plugins-main, I cannot tell what exactly has
changed. An attempt to install your binary package in intrepid broke a few
dozen dependencies, which cascaded into a landslide. Sorting those out
seemed too painful, so I jumped the gun and installed jaunty.

During the week that followed, I had a few crashes. Several were pretty
mild, such as compiz (or something else) becoming corrupt, with all
windows except icons turning white, and initially non-responsive. I could
make them active again by switching to a VT and back, and then replacing
compiz brought everything back to normal. The worse ones lead to a total
lock-up of the system; in one instance I got a black screen with the live
cursor, but nothing else seemed to work; a few other times the machine
froze with partially updated windows and without any trace in the logs.
Today I got the first SEGV in the server that I can report:

Backtrace:
0: /usr/X11R6/bin/X(xorg_backtrace+0x3b) [0x813518b]
1: /usr/X11R6/bin/X(xf86SigHandler+0x55) [0x80c7be5]
2: [0xb8074400]
Saw signal 11. Server aborting.

Every time the crashes coincided with my activity of some sort, and I have
a feeling that with too many things going on and a lot of resources used
it is more likely to crash. Once it crashed when I tried to open a menu in
gimp; and today again it crashed when I used gimp to open half-a-dozen
full-size screenshots.
