Growing up, on all the CRTs I used for console gaming, I never noticed the empty lines because of the color blooming and lack of sharpness. Can you point me to some of these devices so I can read more about them?
They were very common in the Amiga world, as I already mentioned.
Mainly for using a 'professional' SVGA monitor on a standard Amiga. Which became popular in the mid-90s for people who were still using their Amigas, and SVGA monitors had become cheap and commonplace. They were nice upgrades/replacements for the aging Amiga monitors.
Is it something like this ? : http://amiga.resource.cx/exp/highgraph
I'm no Amiga guru, but I think I've seen some adverts for those devices in magazines from the late 80s (88 onwards) to early 90s (~93 ?).
This one supports a proper resolution of 832×620 pixels (non-interlaced!) in 4096 colours @31.25KHz (h-freq.)
That's Super VGA. If this would had been a stock item in the A2000, the Amiga may had lasted a bit longer.
Our old 20" monitor we had in the early/mid 90s was Super VGA capable, by the way, even tough it wasn't multi-sync.
It had BNC connectors for RGB and H/V sync on the back and several control knobs for h/v-sync.
As far as I remember, this was an issue when switching between 640x480 and 800x600 VGA modes.
I think we left it configured for 640x480. Or did we use an in-between resolution for Windows? Can't remember anymore.
Anyway, what we had wasn't a typical "VGA monitor", but a professional RGB HV monitor for all kind of serious use.
It's a shame I can't remember its name anymore.

Jumping back to this real quick, the corruption was basically random pixels filling up any part of the screen that wasn't being updated.
But adding a sound card has fixed this, it now runs correctly just like the other unit posted earlier:
That's interesting! Perhaps that demo is using its internal mod(?) player for timing.
Sorry, it's been a while since I ran this demo.. 😅
