compiz - Feb 2007 - Blur problems

I am having a few problems with blur which I notice other people
are having too.

Focus blur works perfectly (although only with 4xBilinear)

When I start blurdemo, that works too.  The problem is that sometimes
changing the filter type crashes compiz.  If I run it under a debugger
it starts working again.  All the filter types work with blurdemo.

Blurset also works in that it sets the hint on the window, but the
window does not get blurred.  The only applications that work are
gnome-terminal and blurdemo.

I am using nvidia 6800XT with nvidia binary drivers (9631 - but also
same effect with 9742) with xorg 7.2

Using a source blur filter with radius greater than one texel is not
currently supported as it will not work with the current decoration
interface but I plan to fix that eventually.

Any more details you can provide related to this crash would be useful.

Destination blur was only allowed on windows with an alpha channel
before but I've changed that now.
