If you mean the visual being cleared between each polygon or arc,
that is because you have ggiFlush() calls inside your drawing functions in
funcs.c. Don't do that, let the GGI or the user program or the mansync
helper decide when to flush. You are in effect forcing SYNC mode for
those primitives by doing that.
There is still something else going wrong, to cause those
screen-clears - I think it is because we still expose and use
miCopyPaintedSetToVisual() (and the paintedSet type in general) outside of
the stubs code. That needs to go away. When we use the X-target, we are
no longer drawing onto our allocated PaintedSet, but we still draw the
(empty) paintedSet to the ggi_visual anyway |-<.
Anyway, when I removed those two ggiFlush() calls, I got a proper
(and very fast) stream of polygons and arcs to the screen. I also began
to trigger an Xlib bug quite often |->. It seems that demo.c is not only
useful for stress-testing the stubs rasterization code (which still has
one infinite-loop lockup bug which occasionally shows up in the rectangles
test), but now that the XMI X-target is working, it is also useful for
stress-testing the X-server itself |->.

Done.
