This is a known issue.  Basically its up to the application to "clip"
rectangles for UpdateRect as they are basically passed directly to X.
Supposedly this is for speed reasons.

I am not positive but I think it only barfs when the rect is _fully_ off
screen.

At the very least this needs to be documented, but IMO this should be
fixed.

Take it easy,
