This is probably requires a complete rewrite of your demo screen, but what
if you used a horizontal interleaving to reduce the size of the flashing
pieces?  Think interlacing, turned on it's side.  Instead of drawing a standard
48-pixel display twice.

Frame 1:  P0  P0  P0  P1  P1  P1
Frame 2:    P0  P0  P0  P1  P1  P1

The flicker might be less noticable.
