Did you try to grab the X server (not simply the input)?
This should stop any visual updates.

On a more "naive" approach, ksmserver could dump the screen into a pixmap, open
an override redirect window (unmanaged window), in doubt raise it (i think
you'll have to use X11 directly, iirc. Qt only raises by windowmanager requests
- i however also guess for your case it should be sufficient that it will be
initially put on top of the stack anyway) and paint the dump onto that curtain
(while closing the stuff below)
