For us normal Amiga types, this is called "Non interlaced"
Where alternate "half frames" are absent. That gives us the lines without
information in non interlaced modes.

called flicker. You can call it what you like.
> Now I claim the following:
> -flickerFixer should really be called jitterFixer.
Call it whatever you like, but for heaven's sake, go away.
