Sanitarium is an adventure game, originally released in 1998. It was later
re-released with Win XP compatibility. The problem is reproducible in both the
original demo and the newer GoG.com release.

The problem: as you move your character by the mouse, the movement of the
character as well as background animations are hanging frequently (until you
release the mouse).

With the now default OpenGL DirectDraw renderer the problem is reproducible
out-of-the-box:

Changing ddr to gdi *does not* resolve the problem (as of
wine-1.3.29-274-gc9a8d3b). I think this commit only made the issue visible, the
real problem is somewhere else.

This might be a dupe of bug #28377:
+ regression testing resulted the same commit; reverting to gdi doesn't help.
+ the issue is somehow related to the mouse pointer on the screen. Not
specially to mouse movement but the visibility of the mouse pointer as well.
E.g. when your character is climbing up/down the stairs the mouse pointer is
invisible by design. The problem cannot be triggered during that time period,
even if you move your mouse like mad.
- I can't reproduce the problem in Heroes of Might & Magic III (reported in bug
#28377).

Steps to reproduce the problem in Sanitarium demo:
1. Install...launch by SNTRM.EXE (you can safely ignore the warning message
about the incompatibility with Windows NT platforms).
2. You can control your character by pressing and holding the right mouse
button, and moving the mouse to the desired direction (needs a little
practice).
3. As you move your character, you can observe that his movement comes to a
halt from time to time (until you release the mouse).
4. Another occurrence of the problem (background animations): move your
character up the stairs, to the statuette. Below the statuette there is a
waterfall. Without pressing any mouse buttons, move the mouse pointer across
the screen -> the animation of the water is hanging until you stop moving the
mouse.
