Is cairo_surface_flush() drawing anything?
Please send the log output. We might also disable/enable special omapfb code
in DirectFB.
Here is the log:

cairo_surface_flush don't show anything. Maybe it's my fault when I define
or when I use the surface. There's no way to enable DSFLIP_ONSYNC on omapfb?
What's the correct way to make a flippable cairo_directfb_surface??
If I do something like this, the result is the same:
dsc.caps=DSCAPS_PRIMARY | DSCAPS_FLIPPING;
Should be fine.
while(1)
{
surface=cairo_directfb_surface_create (dfb, primary);
cr=cairo_create(surface);
//DRAW SOMETHING WITH CAIRO
usleep(100000);
cairo_surface_flush(surface);
primary->Flip(primary,NULL,0);
cairo_destroy(cr);
cairo_surface_destroy(surface);
cr=NULL;
surface=NULL;
}
If you clear/render to the whole surface each time it should work.
