I've been playing Phantasmagoria lately and the game runs fine... except it has an extreme amount of video tearing when using Dosbox.
I've played this game on a computer running DOS and there is a little tearing there as well.. but nowhere near as much as I get in Dosbox.

I run Dosbox 0.72 at the default settings.. however, I've tried fiddling with almost everything to no avail.

I'm using Vista 64 bit.. but I also tested it on my old XP computer and it's the same there.

Here is a screenshot showing how bad it is -

Is there anything that can be done about this?
