Please test with lock stock DOSBox or keep your questions in the Dosbox-x thread. Dosbox-x is already so far forked from lock stock Dosbox, that it makes no sense to ask in the general forum.

Good, then that's sorted out 😉
Can you provide a picture of how it is supposed to look. I don't see the tearing

Yes, usually appears in the bottom part but can be also a bit higher (always under half screen). You can reproduce it easily and no special config are required...

What do you mean? My cfg: https://hastebin.com/afoqohinan.makefile
Zool2 is 1MB, and is easy to test: it always had this bad tearing when running at decent speed (cycles 12000, or it will play in slow-motion) on modern displays...

Won't change. Please can you test it? I'm sure is not a user custom config dependent bug...
Maybe it was the same on real 386/486 though...
