Is it really needed to upgrade fully from the SYNC mode of XGGI to an
ASYNC mode to obtain this mouse pointer effect?

Even in SYNC mode? In that case, it may be sufficient to flush the
region surrounding the desired pointer location to update more
frequently than the rest of the screen. (You may have some flickering
depending on the pointer background, but well...)

It may be enough. Julien really needs more a (working) hack for visual
appeal than a technically sound solution. He aims a production environment
and, apparently, that mouse lazyness is the only thing that his customers
dislike. That's a perceptual problem but well...
Adding a few ggiFlushRegion() to XGGI (in the pointer management functions)
should not be so difficult. (Julien did you use a binary distrib. of
XGGI or did you recompile it?)
The primary issue is probably that someone needs to tell Julien where in
the XGGI source he needs to add some libggi calls... Does somebody
know here?
By accident, I happen to (sort of) know the kind of system Julien uses.
It may be very nice for GGI to trigger more interest from this area...

the only kind of picture that floats around me for the time being...;-)]
