My rev 2 has the flicker, much like the refresh rate of the display is
slower than about 30hz. In fact, you can see the LEDs across the panel
flicker as well if you look close. And, the flicker get's worse when you're
playing.

But... I don't have the zap. So, I figger that it's just a "no CPU time
available" issue on the Z80.
