this is how /sys/src/cmd/vnc/draw.c was changed to not "mouse turd" on
vesa. have put the changed file in contrib at:
/n/sources/contrib/cinap_lenrek/draw.c
didnt made a patch because its just a work arround, not a real fix.
cpu% diff -c /n/dump/2009/0923/sys/src/cmd/vnc/draw.c draw.c
/n/dump/2009/0923/sys/src/cmd/vnc/draw.c:107,112 - draw.c:107,113
updatescreen(Rectangle r)
{
int b, bb;
+ Image *i;
lockdisplay(display);
if(r.max.x > Dx(screen->r) || r.max.y > Dy(screen->r)){
/n/dump/2009/0923/sys/src/cmd/vnc/draw.c:117,129 - draw.c:118,138
}
}
+ b = Dx(r) * pixb * Dy(r);

+ if(i = allocimage(display, r, screen->chan, 0, DNofill)){
+ loadimage(i, r, pixbuf, b);
+ draw(screen, rectaddpt(r, screen->r.min), i, nil, r.min);
+ freeimage(i);

bb = loadimage(screen, rectaddpt(r, screen->r.min), pixbuf, b);
if(bb != b && verbose)
fprint(2, "loadimage %d on %R for %R returned %d: %r\n", b, rectaddpt(r, screen->r.min), screen->r, bb);
