Hi,

yes it "happens" on a real machine, it's not a bug but a way to get the 
raycaster to run at the desired framerate.

Video from my real STe: http://dhs.nu/video.php?ID=154

If you configured Octlayser (notice the S and not Z (Octalyzer is an Amiga 
program)) correct it shouldn't flicker on a real STe. Eg the number of 
nops to wait for the lower border removal. It is configurable to be able 
to support accelerators. Then it also depends what replay routine you have 
loaded. Some replay routines uses the blitter and if the blitter is active 
during the time the lower border is going to be removed, it will flicker 
that vbl.
