In game menu with only half of screen covered.

For this bug report I'll concentrate on Thief (The Dark Project), but I'm
seeing this problem in a lot of places.  In brief, only the top half of the
screen is visible in certain graphical modes.

In more detail: Thief seems to use four different graphical modes, each with
different behaviour.

1. The first mode, used for the menu screens on entry to the game, work
normally.  I'm doing this test with a wine virtual desktop at 640x480
resolution (and my real desktop is 1280x1024).

2. On entry to the game it uses hardware 3d graphics that runs very slowly. 
This seems to be a known problem with Thief, though I can't see a bug report
for this.

3. Hitting ESC brings up the in-game menu which normally replaces the entire
display; in this report only just under the top half the screen is visible. 
Fortunately I can see just enough of the configuration menu to select software
3d graphics.

4. Software 3d graphics used to work tolerably (in a somewhat earlier release,
maybe 0.9.59?), but now I see only the top quarter or less of the screen!

I'll try and attach some screenshots to illustrate this.  Um -- how am I
supposed to add more than one screenshot in this message?  I've attached an
example for case (3).

This is with Wine 1.0-rc5 built from git, but I've been seeing this problem for
a while now.
