Very similar artifacting is seen for Planescape Torment with ddr=opengl, which
is also an Infinity Engine game. See discussion in bug #5535. If it is indeed
the same problem, Stefan has a theory about the cause (see comment 74):

> Yes. I think the problem is that wined3d can't read the color keyed surface

> draws a sprite, and when it moves the sprite it draws the old contents back
> rather than redrawing everything.
