Moreover it seems that disabling RenderAccel has good effects on various kind of graphical corruption problems that I was experimenting in kde applications (these graphical problems appeared after 173.14.15).
I would want, if possible, to receive some feedback from NVIDIA people at least to know if they are aware of these problems.
I installed the release 180.22 for testing seeing if the freeze still happens. Meanwhile I discovered that the graphical corruption that I was experimenting in kde application depended on the "--loose-binding" option in compiz. Removing that option those bugs and similar bug that I saw in rdesktop and openoffice disappeared. compiz-manager was responsible for starting compiz with the guilty parameters.
