there is still a bit of flicker. not as much, but still there.. if I
reboot in 8bpp and just do a loadimage(screen); there is no flicker at
all.
performance is the same in all 3 cases (~ 80fps in a term the size
that the 'window' command defaults to :)
i guess the solution is to store the pixels in screen->chan format,
since the benefits of loadimage(screen) are huge. not that i'll
bother with XaoS, but it's a good thing to keep in mind for something
as graphics intensive as devtv.
