WORKS with compiz enabled

with "loose bindings", problem with window textures not updating (for example, scrolling in firefox is not visible until compiz restarted or turned off). But this setting is primary for nvidia.

virtual entry beyond 2048x2048 in xorg.conf results in white screen with compiz enabled, regardless of resolution (even in clone setup) (without compiz works everything)
