So the graphics for Windows Hardware acceleration and DOS Hardware acceleration look very similar. However Windows only effectively offers 640x400, which is a squished 640x480 picture.

This is incorrect BTW. The UI is stretched, but the game is not:

I repair voodoo 3/4 for fun and often see exactly this picture

Yeah, this is what I showed on the original video. But the memory check is fine and it only happened so far in this game (I tested 10+ other games, with glide as well as other accelerators). As mentioned Lands of Lore 2 also doesnt support V3 and you can only activate it after patching the game, which then still doesnt support the card and only after copying a ovl file there, you can select it. It can still be a memory issue of course but it would be super weird.

Have you any idea what additional test could help to pinpoint it?

Ah, alright. That might make it even worse, depending on how you look at it. Either way, you have 80 additional pixels on Glide to work it, making it the superior mode in this game.

I also was pointed towards another thread where someone stumbled over the same issue:

Lands of Lore II - its working in EMS mode (sound card is mandatory..) with SB IRQ7, i triead all Vooodo 3 drivers, all are working, but all have some display artifacts problem.
Here i have problems, i most of the game start but not everytime and im same setting and boot session i have i picture some glitches.. Maybe they could be mitigated by some glide variable or other fix..

Solution found, thanks to Maverick from the Retrotink4k Community: The game needs to be run in Windows, but using the DOS Startfile (after doing the separate dos setup, otherwise it crashes).
That way it will run the DOS Version 1.30, with working 3dfx acceleration and no glitches, full 640x480.
