It seems your objects are small enough, few enough, and shallow enough
that you could be using sprites.  Is there some basic reason why you
aren't?  If you switch from Bobs to VSprites, your code won't change
much, and you can get perfectly smooth and flicker-free animation
without double buffering.  You will also be able to use different colors
for them than your playfield, though I don't know if that's an issue for
you.
