After a restore, Counter-Strike is not drawn completly

I've found that wine won't draw correctly Half-Life games (mods too), which are
in OpenGL, after an alt-tab (minimize). It has begun after a kernel,
nvidia-drivers and Xorg update.

When any HL game is started all is fine. After the first alt-tab the game
"window" is cut (see the attachments). It happens even when the game has the
same resolution as my screen and when I do ctrl+alt+arrows (change the current
desktop) since it minimizes the game. I have tested with a old Half-Life
(without Steam) and the bug is reproduced too.

I'm using Gentoo Linux, kernel 2.6.32-gentoo-r7 (before 2.6.32-r3),
nvidia-drivers-256.35 (and 195.36.24 was tested too) (Asus 285 GTX),
xorg-server-1.7.6 (before: 1.6.5-r1).

Other attachments: game effects are affected as well resulting in possible
cheat exploits. Notice that these are windows captures (alt-printscreen).
