I believe that the "flicker" problem that Blaine is talking about isn't
actually flicker per se, but the effect seen when certain color combinations
are scrolled in multi-color modes.  For example, if you have yellow text on a
black background, and that line of text is scrolled upwards, you might see a
momentary ghost text line on the screen for a fraction of a second,
presumably since the text is being scrolled by the blitter, which can only do
one bit plane at a time (it can do 2 bit planes without noticable flashing,
but for 3 or more it poops out).  Has anyone out there ever seen a terminal
program that didn't have this problem in an 8-color mode?
