[Bug 7585] Thief: the dark project hangs on 'esc' keypress in game

Austin,
I did some testing a while back.
I narrowed it down thus:

0.9.28
esc is fine (very slow rendering)

0.9.29
program dies at startup!

0.9.30
esc hanging bug appears

Discussion with StefanD leads me to be pretty certain the bug appears due to
the new Render Target Locking code introduced around 0.9.29 somewhere. (see
comment 10)

The next stage in bug hunting was to take a the render surface using 
IWineD3DSurfaceImpl_SaveSnapshot or similar.

my IRC log:

14:25 < stefand> thats odd. take a look at IWineD3DSurfaceImpl_SaveSnapshot
14:26 < stefand> you can write a snapshot of the surface to the disk on unlock
14:26 < stefand> and see if the content is contructed correctly, or if there's
some problem above that
14:26 < stefand> but you may rather try to use IWineGDISurfaceImpl_SaveSnapshot
instead of the D3D one
14:27 < stefand> because the GDI function writes the snapshot from the system
memory copy, while the 
                 d3d one draws from gl.
14:27 < stefand> it doesn't arrive properly at gl, so the D3D savesnapshot will
give you a black 
                 screen
14:27 < stefand> you can add a IWineGDISurfaceImpl_SaveSnapshot in UnlockRect,
in the render target 
                 codepath(that calls the ActivateContext(... CTXUSAGE_BLT))
14:29 < ahurst> stefand: alright, thanks for your time, I'll give that a go and
see where I get to.
