Re: Desktop freeze with 270.x drivers, KDE 4 and Compiz
X.Org X Server 1.10.1
Linux 220.127.116.11 x86_64 Gentoo
I've also applied the queue size patch that I found somewhere in this forum; this seems to have improved but not solved as it still happens. The symptoms are the same and yes, it appears only with 270.x drivers.
Bug report attached
