<pre>The game is available on Steam and needs Wine to run.
The main menu and all the objects in the game appear transparently, see this
screenshot for comparison (images on the right show the correct behaviour,
images on the left is the current state): <a href="http://imgur.com/aDhYehq">http://imgur.com/aDhYehq</a>
The problem doesn't occur with the binary Nvidia drivers (340.76).
Regression introduced by

nv50/ir: fold MAD when one of the multiplicands is const
Fold MAD dst, src0, immed, src2 (or src0/immed swapped) when
- immed = 0 -> MOV dst, src2
- immed = +/- 1 -> ADD dst, src0, src2
These types of MAD patterns were observed in some st/nine shaders.
Reverting the commit on current git fixes the problem for me.

To reproduce the problem in the demo version you need Wine (preferably the
latest development version) and a Steam account. The game needs native d3dx9_36
('winetricks d3dx9_36').
