What I wonder is what changed too, because when desktop effects first
appeared several versions ago, I was able to use VNC and everything
worked perfectly.  (I think it was about a year ago that it stopped
working).  So at some point the handling for this changed in a way
that open source drivers adjusted to, but everyone else writing
drivers probably wasn't even aware of.

> When using the nvidia-restricted or some ATI drivers and compiz desktop effects the vnc server will not refresh the screen. This is being caused by the xserver not getting "damaged" by the nvidia-restricted drivers. Linked bugs confirm this is not an issue on intel chipsets or nv driver.
