compiz.real crashed with SIGSEGV in groupDestroyCairoLayer()

Binary package hint: compiz

This is an automatic bug report.

I have, by the way, the impression that the support of my graphical card is far from being as smooth in Jaunty than in Hardy (I never used Ibex).
When I use compiz (Kubuntu), my computer becomes really slow (several seconds to change of desktop for example).

Here is an part of lspci :
